Sector II

Sector II plan

The relationship of Sectors I – III


This sector was visited and reported for the first time in 1982 (Drew 1982, Thomson 2001).


The sector consists of a tightly grouped assortment of carefully constructed large buildings, walls and smaller structures arranged around a central plaza with several outlying structures of lesser quality. The group sits upon a flat bench with a steep, rising embankment behind and a steep downhill slope to the front. Another levelled, plaza like, area is situated just below (NE) which may have been a pond or water feature now dry and filled in. The only present water source identified for the region, a spring, is located just above to the south of the plaza. Remains of a stone lined channel acequia originating at the spring is indicated on the site plan. This leads into a nicely made, sunken, stone lined enclosure (8) resembling one of the fountains or ritual baths at Machu Picchu or Wiñay Wayna.


The main buildings (1-7) have shaped corner blocks of quartzite and coursed slabs, with blocks for the walls. Remains of clay indicate that the structures were plastered. Roots and trees have crumbled parts of most structures, but some walls are standing close to the original height. Building 6 has a back wall height of 14 feet. 1, 2 and 6 had gabled roofs; number 12 may have as well. This is undetermined for the remainder. Buildings 1-7 had internal niches and some windows. Minor details are lacking because of surveying demands created by the unexpected size and extent of the findings.


By contrast, structures 12-14 are of poorly constructed, mortared fieldstone without niches. Structure 13 has a low walled open side and a long low window lined with adobe blocks.  Four rocker-shaped grinding stones for corn were found inside, made of granite. Building 12 appears to have been modified by an internal enclosure.  It is likely that local farmers or herders used these buildings in later times. Building 12 could have served as a caretaker residence or entrance control for the main group as suggested for structure 12, Sector I.


The central section of the group has multiple passageways that open out to a long filled, low walled platform/walkway that forms an overlook of Huayna-Machu Picchu and the Veronica Range beyond. The long axis points to and views the Overlook Temple (Sector V).


Building 2 has a window that opens into a short corridor viewing Huayna Picchu. Structure 3 is a small structure 10 feet by 10 feet with 4 internal niches. The one entranceway faces 50 degrees toward Huayna Picchu. It size and location suggest that it was a shrine.


Feature 4 is a courtyard like area between building 2 and a long sunken enclosure recinto (5) It is closed by a wall at the end that faces Huayna Picchu. Here an entranceway with an alignment of 50 degrees opens to the outside platform/walkway.


 Structure 9 is a low wall slightly above the plaza level that measures six feet high on the downhill side. The wall merges into a raised earth platform, which takes a curious jog to terminate at structure 10. The wall and mount may have been used as a ritual walkway to reach a shrine. This feature is a small 10 feet x 10 feet U shaped structure masma  with the open side facing inward to the plaza at 230 degrees.


Building 7 is an interesting feature. It is an unusual structure 30 feet by 30 feet with internal niches and a single entranceway facing into the plaza. The back or Huayna Picchu side lacks windows and has five rectangular niches. The two sides perpendicular to the entrance have matching long windows. The workmanship is in the best Vilcabamba style, with shaped corner blocks and carefully fitted, coursed, wall stones. The location gives immediate access to the bath/fountain (8) and water system. The building remains an enigma deserving further study.


A steep escarpment falls off to the northeast. Some 20 metres below is a sizable pampa area with swampy depressions and a profusion of water plants.  This may have been a pond or developed water feature associated with the group above. It was used by both Bingham and this recent expedition as a base camp.


A most notable aspect of this Sector is that the main group is orientated to face Huayna Picchu at an azimuth of 50 degrees, and the Overlook Temple at 320 degrees. This creates a sight line to each at a right angle or 90 degrees to each other. It this is not coincidental, then the placement of the temple and/or Sector II had to be carefully planned and by design. Alignment on Huayna Picchu and its Three Windows shrine that looks back on the main Sectors suggests that Huayna Picchu may have been an important spiritual focus of sector II (Ziegler-Malville 2003).

Orientation towards Huayna Picchu:  Diagram


Sector II has a number of unusual features that appear to have had a ceremonial function. The main group is orientated to face Huayna Picchu at an azimuth of 50 degrees. The long axis of the group points to the Overlook Temple at 320 degrees similar to the long axis of Sector I. Near the summit of Huayna Picchu is the House of Three Windows, a shrine containing a replica stone closely resembling the Llactapata ridge that focuses attention on and is in alignment (230 degrees) with the Llactapata sites (Ziegler-Malville 2003).

Three windows shrine on Huayna Picchu


A ritual fountain/bath along with a pond suggests that water was an important design element here as well. The small U shaped shrine (10) faces inward to the plaza and hillside. Its focus is directed toward the spring and only water source for area. The American anthropologist Susan Niles describes similar Incas sites as water shrines or moyas  (Niles 1999).


Features at Sector 2 suggesting water ritual include fountains, a canal leading from the only current water source in the area, a platform excavated from the hillside, and the evidence of an artificial lake.


Buildings 1, 2 and 6 could have served as temporary lodging for important parties travelling on official business, state sponsored pilgrimages or ceremonial processions to and from Machu Picchu as a sort of high status shrine and tambo  with a ceremonial purpose. Like Wiñay Wayna on the eastern road to Machu Picchu, the main Llactapata groups are situated several hours travel along the western approach.


There are similarities between the two sites. Wiñay Wayna is at an altitude of 2,600 metres and a distance of eight kilometres from Machu Picchu.  The Sector II group is at 2,700 metres and about the same distance by the original western road. Both are designed around water features. Reinhard believes that Wiñay Wayna was built as a ritual-stopping place along the road to Machu Picchu. The similarities with Sector II suggest that it may have in part served the same function.


Sectors I and II have certain architectural similarities, in particular the unusual division by sunken corridors, which suggest they may represent the principal upper and lower divisions, hanan and hurin, of the archaeological zone, in the duality common to Inca urban design and socio-political administration (Gasparini and Margolies 1980, Hyslop 1990). The Eastern and Western Sectors at Machu Picchu, separated by the main plaza are identified as such by Alfredo Valencia and others. (Wright-Valencia 2001)

Sector III - The Usnu Group

Sector III plan

The relationship of Sectors I – III



Located some 100 metres from the uphill side of Sector I and only 30 metres higher in altitude, this sector is associated with Sector I.


Structure 2 is a long building with three entranceways facing east into a small plaza. The roof was probably gabled but considerable breakdown has occurred. No windows are evident. It measures 90 feet by 20 feet with the back wall 9 1/2 feet high. The alignment is cardinal north south.


Structures 3 and 4 border the north side of the plaza. 3 is low walled with the slope falling off to the north and west leaving a higher north-facing wall with an outside niche. Structure 4 is more interesting. Most wall stone is a shaped white granite similar to that of Machu Picchu making the architecture unique for the area. The material must have been imported from either near Machu Picchu, or some closer isolated granite dike. A single internal niche faces east toward the one entrance. A passageway leads down through a gateway between structures 3 and 4 to feature 5, the most important structure of the group, which appears to be a Sacred Platform or Usnu.


The Usnu is a 60 feet by 40 feet raised, earth filled platform, enclosed by a five feet high retaining wall. It is connected to building 4 by a 60 feet long low wall. Stone steps lead onto the platform from the northeast side. The platform is aligned 20 degrees by 110 degrees. and overlooks Sector I below.


Another low wall, 40 feet long, leads off from the northwest corner of building 2 at 330 degrees. Beyond the wall is a low walled rectangular structure (1) that is similar in size and placement to outlying structures at other sections. It may have been built for a caretaker or attendant.


The main buildings and plaza are aligned with cardinal directions. Johan Reinhard has written of the importance to the Inca of cardinal directions, equinox alignments and their unique relationship to sacred mountains at Machu Picchu (Reinhard 2002) Although alignments would somewhat differ, it follows that this may be true for Llactapata sites as well.  The northwest wall of the plaza, aligned at 335 degrees, is in directional line to the Overlook temple. However, it was not possible to establish whether the temple can be seen from the plaza. A similar wall running out at an angle from a building at Cota Coca creates a sight line to the water shrine Pinchu Unuyoc near Choquequirao. (Ziegler-Thomson 2002)


An important feature is the large usnu platform. The term has several meanings. Usnu is used to describe a stepped platform upon which the Inca was seated from an early description by Guaman Poma (Poma 1956 [1613]). An usnu has also been described as a place to view sunset with markers on the horizon. (Zuidema 1986). The great usnu of Cusco, Usnu Capac, had a central pillar for astronomical sighting (Moseley 1993).  The name appropriately describes raised platforms associated with ceremonial sites.


With an alignment of 110 degrees and 20 degrees, the platform is orientated close to the December solstice line for the rising sun of 112 degrees noted by Johan Reinhard for Machu Picchu (Reinhard 2002). As no significant summits are close to this alignment to suggest a topographic focus, nor does the platform align toward Machu Picchu, it is possible that the primarily ritual activity related to the December solstice. Overlook miradores and raised platforms are common throughout the region but few are of this large size. Only hill top platforms at Choquequirao and Cerro San Miguel are larger (Lee 2000, Ziegler 2001, Reinhard 2002,). The size suggests that this was a very important ceremonial location. Sector III requires additional study.


There seems to have been an attempt to establish the main sectors of Llactapata  1-3 along a direct east-west line, as the centres of those sectors depart from that  east-west line by less than 1/3 degree.

Sector IV - The Reinhard Group

Sector IV plan


During 1985 Johan Reinhard conducted an exploratory investigation of the upper regions of the Aobamba drainage. He visited and surveyed the high site of Palcay (3600 metres) previously documented by Bingham (Bingham 1913). While descending down to the Urubamba Canyon, he surveyed and reported the building now identified as Sector IV. (Reinhard 1990).


Following his description and map, the site was re-located where indicated on a lofty shoulder of the Llactapata ridge at 3000 metres altitude, among tall tree-ferns. The remaining walls are badly deteriorated. The main structure is a long (120 feet) narrow building with 12 entranceways spaced along the sides. No niches are visible. The building follows the slightly curved contour of a small hilltop. 


A number of equally spaced holes are centred along the inside floor.  All have been opened by treasure hunters, huaqueros. They appear to have been stone lined chambers similar to others that have been observed in the Vilcabamba. (Ziegler 2001, 2002). Three smaller low-walled rectangular structures are located nearby. The building is situated near the route of a likely Inca road that connected Palcay above with Llactapata and the main westward Inca road below.


Similar long structures with multiple entrances have been identified as meeting halls, kallankas, such as the largest building at Machu Picchu, located outside and above the main gateway (Wright-Valencia 2000). These large buildings seem to be located near or are part of a larger site such as at Choquequirao, Cota Coca and Machu Picchu. It would be unusual for a meeting hall to be placed as an isolated structure in a remote region. 


Some long buildings have been identified as storehouses.  Examples are a group between the upper and lower Plazas at Choquequirao and a long isolated building with multiple entrances and windows at Sapamarca. (Ziegler 2001)


Storehouses were frequently placed in a high open area for ventilation and other reasons such as at Ollantaytambo (Protzen1993). The holes or chambers in the floor present an enigma. Reinhard thought the holes were dug by huaqueros.  However, several were now found to have visible stone linings.  From excavations at Corihuayrachina similar chambers were found to contain simple offerings and low status burials (Ziegler 2002). 


 It is interesting that the alignment of the east wall is 40 degrees, creating a sight line to the summit of Huayna Picchu. An azimuth of 340 degrees for the opposite or north end offers a sight line down the Urubamba Canyon to the site of Sapamarca. The building may well have been a storehouse, located below the frost zone on the road to Palcay. Local residents may have used it as a convenient mausoleum at a later date, during or following the decline of Machu Picchu. The three low walled structures may have been simple wood-sided huts for a caretaker family.

Sector V - Group A and Group B


This complicated Sector encompasses a large area of the lower ridge dividing the Santa Teresa Valley and the Aobamba drainage, terminating when the two river merge in the Urubamba River and Canyon at an altitude of 1,500 metres. The ridge runs from 2,800 metres down to a partially clear saddle at 2,600 metres. From the saddle, the ridge rises steeply up into several rocky crags with steep cliffs on either side before again plunging downward. The upper portion is cloaked in heavy dense forest and thick, nearly impenetrable vegetation.  A rough trail reaches the saddle from the Santa Teresa valley side. A seasonal hut and several cornfields account for the cleared areas.


Four main groups were located and incompletely surveyed; Groups conjuntos A and B, the Overlook Temple and the crag top platforms. Several freshly dug holes indicated that the local farmer had visions of buried treasure. The central feature is the solitary, unique two story building perched on a ledge viewing Machu Picchu, first reported in 1982, and now described as the Overlook Temple. [3]


Sector V Group A


Group A: This feature is a rectangular walled compound kancha measuring 75 by 55 feet enclosing a long three room, badly crumbled building. The outside wall is six feet high and three feet wide of crude slab construction. The alignment is cardinal with east facing entranceways offering a sight line to Mt Machu Picchu.

Sector V Group B


Group B: Located two hundred metres down the ridge and at a slightly lower altitude, this group of seven buildings is built upon a small hill.  A central wall divides the group into lower and upper sectors each with an internal plaza. The alignment is north south with entranceways at buildings 1-5 opening into the two plazas. Building 6 is round with an inside diameter of 16 feet. The entrance faces south. The north wall has three niches. A single window faces east offering a sight line to Mt Machu Picchu.


The extent of scattered foundations and crumbled, poorly made walls suggest that the lower ridge was a settlement of low status workers. The gently sloping and level areas of the long ridge are well suited for agriculture as demonstrated by several recent cornfields located near the saddle. Although this needs considerable further study,  two possibilities are that Groups A and B  were either storehouse groups, qolqas, or administrative centres/residences for the local administrators or karakas. 


These were hereditary heads of kinship groups, ayllus, that worked and managed agricultural lands. The duality of Andean social organization required two for each settlement (Moseley 1993). If so, Group B could have housed the principal or more powerful administer. The round house with window view of Mt. Machu Picchu may have served a ceremonial function.  Additional study is needed.


Platforms and low walls on the rocky crags above may have offered a view to the east of Mt Machu Picchu Mountain, Mt Veronica and to the west of Mt Pumasillo. The summit of Mt Salcantay can be seen to the South.  Reinhard and others have shown these mountains to be particularly important to the Inca. Of interest is that the crags lie exactly on the equinox line from near the summit of Mt Veronica. The line crosses the Machu Picchu Intihuatana and the summit of Cerro Miguel, which has a platform and upright marker stone on the equinox line (Reinhard 2002). The Sector V platforms may have been especially suited to respect sacred geographical features in combination with equinox alignment and other astronomical phenomena.

Sector V - Overlook Temple

Overlook Temple plan


On the lower ridge above groups A and B there is an unusual, solitary, two-story structure perched on the edge of a steep drop above the river some 1200 metres below. Construction is of the finest Vilcabamba style with larger blocks of shaped quartzite utilized for corners and doorjambs. The building contains 14 niches. The one entrance way and two windows open to a balcony or walled, filled platform providing an impressive view of Machu Picchu, the Veronica Range, Cerro San Miguel, Salcantay and the Urubamba River.


The west-facing wall has two open chambers with niches, which look out on a broad gently sloping area with no visible evidence of constructions. A short wall with two niches extends out eight feet from the northwest corner creating an angled passageway leading onto the front platform. Nearby, a walled path descends toward the Urubamba and the riverside Intihuatana shrine.


The building is cardinal aligned. Its eastern facade and doorway focus a sight line to Machu Picchu Mountain in alignment with the huaca site called the Intihuatana in the Urubamba Canyon below. This is the line the sun would be seen to follow during equinox for a viewer at any of the three locations. The ice summits of Veronica and Salcantay are also visible. The summit of Cerro San Miguel lies at an azimuth of 60 degrees from the temple. The sun would rise over Huayna Picchu during the June Solstice and be seen close to the summit of Cerro San Miguel when first viewed. Both June solstice and equinox ceremonies could be conducted from the temple.


An unusual feature of the location of Overlook Temple is that it lies close to the extension of the long axes of the Llactapata Sun Temple (Sector I), the possible moya of Sector II, and the usnu of sector III. A person standing on the courtyard of the Sun Temple facing the June Solstice sunrise would find the Overlook Temple to be 90 degrees away from the sun. Conversely, a viewer at the Overlook Temple would have the Sun Temple at a right angle to the rising sun during the equinox.


This solitary, unusual structure, first reported in brief outline in 1982 but not mapped, seems to have been a most important ceremonial feature of the Llactapata archaeological zone (Drew 1982), The setting, construction, design, external niches and platform mirador suggest that the building had an important ceremonial purpose.


Sight lines to sacred topographic features in relationship to equinox and solstice alignments suggest that solar rituals and ceremonies were primary activities. A sight line orientated directly east, passing through the huaca Intihuatana at the sacred Urubamba River, Wilcamayu, to Mt Machu Picchu is particularly significant. The Intihuatana site has yet to be studied. Reported by Bingham, the feature has not been surveyed (Bingham 1913).


Another east-west alignment involves the isolated structure that we have called the Overlook on the lower Llactapata ridge (Sector V: Figure 5). Its eastern balcony faces Machu Picchu peak and provides a view of a stone shrine or usnu down in the Urubamba Canyon that Bingham had called another intihuatana. The Intihuatana site consists of a large sculpted rock, a platform, water channels, waterspouts and basins.


A displacement of the shrine by a few meters to the south would cause the Overlook to disappear behind the cliffs of the canyon when seen from the Intihuatana, suggesting the importance of inter-visibility. There are other visual linkages between structures in Llactapata and Machu Picchu. The Priest’s House of Machu Picchu is oriented toward Llactapata and the setting sun at December solstice10. The house of three windows on Huayna Picchu faces the Llactapata ridge and contains a huaca that replicates the ridge.


However, the location at almost the mid way point between the Overlook Temple and Machu Picchu Mountain would allow an observer to view sunrise near the Mountain, and then sunset near the temple during equinox. Reinhard and others have demonstrated the importance of Mt Machu Picchu to the builders of Machu Picchu (Reinhard 2002, Ziegler-Malville 2003).


The placement of the Overlook Temple in relationship to these important features gives it special significance.

The research expedition revealed Llactapata to be a far more substantial site than has previously been realised


As group after group appeared, some uncovered after five centuries of concealment it became apparent that this was far more than a small compound of buildings described by Hiram Bingham in less than a paragraph. 


There are parallels to one of Bingham’s most important discoveries, Espíritu Pampa in the Vilcabamba, which he only partially uncovered in 1911.  Only later, in 1964, were further sectors revealed and its true significance established, as Vilcabamba La Vieja, the last refuge of the Inca.


Likewise Llactapata, the supposedly insignificant ruin with the unassuming name, ‘high town’, is of much more importance than had been thought.


Many groups and features at Machu Picchu have been identified as having alignment to astronomical phenomena or specific topographic features. (Dearborn 1987, Reinhard 2002). Johan Reinhard has suggested that Machu Picchu was located, designed and functioned as a ‘sacred centre’, with a unique convergence of geographical features, sacred mountains and the Urubamba River giving astronomical and cardinal alignments (Reinhard 2002).  As a closely related satellite of Machu Picchu, this interpretation applies well to the Llactapata site.


Solstice-equinox orientation in relationship with alignments on Huayna Picchu and Mt Machu Picchu indicates that adoration and ritual focus on these special mountains and the sun may have been the primary purpose at Llactapata. If the Sector I group is a sun temple as we suggest, its location, situated to view the sun rising over the Sacred Plaza, midway between the two peaks during the June solstice, gives great ritual importance to the site.


The solitary Overlook Temple seems to be both a June solstice and an equinox feature, placed to view the sun rising near the summits of Cerro San Miguel and Machu Picchu Mountain.  The ridge top platforms also appear to have an equinox purpose from their placement directly to the west of Cerro San Miguel and Machu Picchu.


The Usnu Group, the newly reported Sector III, may also have had an equinox purpose, as the main structures are cardinal aligned.  However, the large, raised usnu is the principal ceremonial feature. The alignment suggests that the main function may have been December solstice activities. The platform would also have been used for different astronomical and ceremonial events.


An alignment relationship with the Overlook temple and sight lines to and from the Sun Temple, Usnu Group and Sector II is a phenomenon, which we suggest, was by design.  At Machu Picchu every feature or construction appears to be planned and aligned with a purpose.  We suggest that the ceremonial groups and features at Llactapata were placed and built in careful consideration of geo-spiritual and astronomical relationships in conjunction with Machu Picchu.  Llactapata was part of a carefully designed network of interrelated administrative and ceremonial sites supporting the regional administrative and ceremonial centre at Machu Picchu.


This should be seen in the light of recent work by John Rowe, Richard Burger and Lucy Salazar-Burger, which places Machu Picchu in the context of Pachacuti’s personal estate (Rowe 1987, Burger & Salazar-Burger 1993). The high status architecture found not only at Machu Picchu but throughout the Vilcabamba and at sites along the upper Urubamba valley is a reminder of the use of this area for royal estates by the Inca nobility (Burger & Salazar-Burger 1993, Niles 1999). 


Llactapata is an important staging post on a network of roads extending from Cusco to Vitcos.  Our investigations have identified the remnants of an Inca road at Llactapata connecting with the ‘drawbridge’ route west from Machu Picchu. Earlier explorations by Hyslop, Lee, Thomson, Ziegler and others have traced roads from the important Vilcabamba sites of Vitcos and Choquequirao (Hyslop 1984, Lee 2000, Thomson 2001, Ziegler 2001). A major road network connecting with extensive Inca controlled regions to the west reinforces the idea that Machu Picchu was the spiritual and administrative hub of a network of roads, regional settlements and state controlled commerce as suggested by Ann Kendall and others (Kendall 1988).


A large staging area and meeting hall outside the main gate and a number of qolqas indicate that Machu Picchu may have been a collecting point for goods arriving from the Vilcabamba to be sent on to the capital or for other distribution. If so, Llactapata would have been an important resting place and roadside shrine for important official parties on the road to Machu Picchu and beyond. We have discussed the similarities of Sector II with Wiñay Wayna, which has been identified as a water shrine and resting-place on the eastern road (the so-called ‘Inca trail’). The Sector II group likely served a similar purpose as a sort of high status tambo with seasonal ceremonial activities.


The architectural similarities between Sectors I and II reflect the division of the site into hanan and hurin sectors common to pan-Andean societies (Gasparini & Margolies 1980, Hyslop 1990).


An area of about one square kilometre suitable for agriculture and the abundance of poorly made structures on the lower ridge in Sector V indicate that quantities of corn and other crops were grown here. The American hydrologist Kenneth Wright calculates that the agricultural areas at Machu Picchu could only have produced enough to feed 55 people.  He estimates that the site housed 300 permanent residents (Wright & Valencia 2000). The Llactapata crops may have been a useful way to supplement food production at Machu Picchu.


The number of simple foundations suggests that the area was also a low-status settlement that may have housed a population of workers in support of activities at Machu Picchu, just as the settlements in the Cusichaca valley are thought to have been (Kendall 1988).  We have estimated the distance along the Inca road to Machu Picchu to be less than eight kilometres.


The identification and study of the Llactapata archaeological area adds significantly to our knowledge and understanding of Machu Picchu as the hub of a complex neighbourhood of carefully placed interrelated administrative and ceremonial sites reaching outward toward distant imperial Cusco and the far Vilcabamba.


The architecture and dramatic landscape of Machu Picchu have always suggested that for the Inca it was a place with considerable depth of meaning and sacred power. Llactapata adds to its significance providing a sun temple, similar to the Coricancha, from which the Pleiades and the June solstice sun rise over Machu Picchu.
