The Guardhouse at Machu Picchu

There is an image of Machu Picchu that appears in almost every travel guide, on tourism agency posters, and in most of the photographs visitors share after being there: the citadel seen from above, with the agricultural terraces in the foreground, the urban sector behind them, and Huayna Picchu rising over the horizon. That image is always taken from the same point, or very close to it: the platform next to the Guardhouse, on the southern edge of the citadel.

The Guardhouse is one of the best-preserved buildings in Machu Picchu, the only structure in the site with its thatched roof reconstructed, and the obligatory first stop for most visitors arriving from Aguas Calientes. But beyond its role as a viewpoint and photographic reference, it is also a structure with its own history and a function within the complex that is worth understanding before continuing the walk into the interior of the citadel.

Where it is and why it is there

The Guardhouse is located at the southern end of the citadel, on the ridge that separates the agricultural sector from the main entrance to the site. It stands on an elevated terrace from which it visually dominates both the access from the path that climbs up from Aguas Calientes and the entire archaeological complex stretching northward. That position is not accidental: it was built at the only point on the southern ridge where an observer could simultaneously control the external access and the interior of the citadel.

The building sits right beside the path that connects the site entrance with the agricultural sector and, from there, with the Main Plaza. Anyone entering Machu Picchu through the southern main gate the only permanent entrance for those arriving from the hillside trail would necessarily pass beneath the terrace where the Guardhouse stands or along the path running beside it. The visual control from this point was complete.

The name and what the Guardhouse really was

The name “Guardhouse” was assigned by twentieth-century archaeologists based on a functional hypothesis: the building’s position, its orientation toward the site’s access points, and its location on the outer edge of the citadel suggested that it may have been occupied by personnel responsible for monitoring the entrances. The name became established in archaeological literature and in tourist guides, and it has been used ever since.

However, the name is an interpretation rather than a verified historical fact. Colonial chronicles do not mention this specific building, and excavations inside the structure have not produced definitive evidence that it was inhabited by guards or watchmen. What is clear is that the building formed part of the group of structures associated with the southern entrance to the citadel, and that its elevated position gave it a visual control function over that sector regardless of the rank or role of those who occupied it.

Some researchers have suggested that the building may also have had a ritual function connected with the Inca cemetery that Hiram Bingham excavated on the slope immediately east of the structure in 1912. That cemetery where more than 170 skeletons were recovered, the largest collection of human remains found at Machu Picchu is located only a few meters from the Guardhouse, and the spatial relationship between the two may not be accidental.

The architecture: the only thatched roof at the site

The Guardhouse is a rectangular building with a simple layout, constructed with intermediate-quality stone walls well built but without the finely finished ashlar masonry of the ceremonial sector and three closed sides with a large opening in the facade that faces the interior plaza and the panoramic view of the citadel. This opening is not a conventional doorway: it occupies almost the entire width of the facade, turning the interior into a semi-open space with direct views toward the archaeological complex.

What distinguishes this building from all others at the site is its roof. During decades of archaeological work at Machu Picchu, most buildings were structurally stabilized walls reinforced and fallen stones replaced without attempting to reconstruct the roofs, which in Inca architecture were made of wood and straw and disappeared centuries ago. The Guardhouse is the only exception: at some point in the second half of the twentieth century, its roof was reconstructed using ichu grass, the high-altitude grass that the Incas used as roofing material throughout the Andean region.

That reconstruction dramatically changes the perception of the building. With its roof in place, the structure stops looking like a ruin and becomes a habitable space, with a scale and presence that allow visitors to imagine what the buildings of Machu Picchu looked like when the site was active. The straw roof gives the structure a texture and color that contrast with the gray stone of the walls and the green of the terraces, and that combination is part of the reason the view from this point is so recognizable.

The viewpoint and the panoramic view

The platform beside the Guardhouse offers the most complete and balanced view of Machu Picchu. From there you can see simultaneously the agricultural sector with its terraces descending toward the valley, the urban sector with the temples and ceremonial buildings, the Main Plaza at the center, Huayna Picchu in the background, and on clear days the outline of Machu Picchu Mountain closing the horizon to the south. It is the only position in the site where all of these elements are visible at once and in proportions that make it easy to understand how they are organized in relation to each other.

This view also has a particular timing worth knowing about. In the early morning, when the mist of the Urubamba Valley is still present, the citadel appears and disappears among the clouds in a way that no other moment of the day reproduces. Watching Huayna Picchu gradually emerge from the fog while the sun begins to illuminate the terraces in the foreground is an experience that visitors who arrive when the site opens at 6:00 a.m. often describe as the most memorable moment of their visit. After about 9:00 or 10:00 a.m., when tour groups arrive in larger numbers from Aguas Calientes, the viewpoint platform can become quite crowded and the wait to take a photograph without other people in the frame can be long.

The Inca cemetery on the eastern slope

A few meters east of the Guardhouse, on the slope descending from the southern ridge of the citadel, Hiram Bingham discovered in 1912 the largest cemetery excavated at Machu Picchu. From that site the remains of more than 170 individuals were recovered. They were taken to Yale University for study and decades later returned to Peru after a long diplomatic negotiation process that concluded in 2012.

The analysis of these remains carried out mainly by bioarchaeologist Elva Torres and later reviewed by the teams of Richard Burger and Lucy Salazar provided fundamental information about the composition of the population of Machu Picchu. Isotopic studies showed that the individuals buried there came from different regions of the Tawantinsuyo, confirming the multicultural character of the site’s population. The analysis also revealed that most individuals displayed bone markers of intense physical activity consistent with agricultural or construction labor, reinforcing the hypothesis that a significant part of Machu Picchu’s permanent population consisted of yanaconas or specialized workers.

The proximity of the cemetery to the Guardhouse has led some researchers to propose that the building may also have had a role connected with the care or administration of the funerary area, in addition to or instead of the surveillance function suggested by its name. This hypothesis remains under debate.

The relationship with the agricultural sector and the site entrance

The Guardhouse stands at the transition point between the exterior of the site and the agricultural sector. From the current entrance to Machu Picchu where tickets are checked the Guardhouse is immediately visible on the elevated terrace above the path. That threshold position between the outside and the interior of the citadel reinforces the hypothesis of its control function, regardless of the debate about who exactly inhabited it.

The agricultural sector that extends northward and downward from the Guardhouse terrace was, in Inca times, the first element of the citadel visible to anyone arriving from the south along the main path. The terraces were not only productive infrastructure: they were also the first impression of the site, the signal that one was entering an organized and controlled space. The position of the Guardhouse above that foreground of terraces reinforces the idea that the southern access was deliberately designed as a sequence intended to communicate the importance and order of the site even before visitors reached the temples.

How to make the most of this stop

The Guardhouse is usually the first place where visitors stop after entering the site, drawn by the panoramic view. That first pause is natural and inevitable, but it is worth returning to this point later in the visit preferably from inside the citadel looking south to understand its position from the opposite perspective: not as a viewpoint looking toward the citadel, but as part of the citadel looking outward.

The interior of the building is worth visiting beyond the open facade. From inside, with the thatched roof overhead, the scale of the space feels very different from what the exterior photograph suggests. The walls, the niches in the stone, and the overall finish provide a concrete sense of what the interior of a functional Inca building might have looked like less elaborate than the temples but built with the same structural solidity.

The terrace immediately south of the Guardhouse, at the edge of the ridge, is the closest point to the outside of the citadel from which visitors can see the road climbing from Aguas Calientes as it zigzags up the mountain. Seeing that road from above the same one you just climbed by bus or on foot places the arrival at Machu Picchu into a topographic perspective that many visitors describe as one of the clearest moments of the entire visit.

The Guardhouse is both the first and the last point of the route for most visitors to Machu Picchu: you pass it when entering and return to it when leaving. That threshold position which in Inca times was a functional condition of the building remains fully operational today. Before entering and after walking through the citadel, stopping here and looking in both directions toward the outside and toward the complex is one of the best ways to understand Machu Picchu for what it truly is: a site designed to be seen and understood from its edges as much as from its center.
