Chullpas Sillustani

On a peninsula jutting into Lake Umayo near Puno, ninety-one stone towers stand in various states of preservation — from intact cylinders to tumbled foundations. These are chullpas, the funerary towers of the Colla people and their Inca successors, built above ground to house the dead in a posture of continued presence. Each tower faces east, greeting the sunrise through a small sealed doorway. The dead were not hidden here. They were elevated.

Sillustani occupies a hilltop on a peninsula that reaches into Lake Umayo, thirty-four kilometres north of Puno. The site is exposed — wind sweeps across the plateau, and the lake surrounds on three sides. The landscape is one of the most atmospheric in the Peruvian Altiplano, and the funerary towers that crown the hilltop seem to have been built in conversation with it.

The Colla (Qulla) people, who controlled this region before the Inca conquest, began constructing chullpas here in the thirteenth century. These are above-ground burial towers — cylindrical structures of carefully fitted stone, ranging from two to twelve metres in height, built to house the remains of elite families along with food, offerings, and personal belongings. The corpses were placed in fetal position, suggesting rebirth rather than ending. Each tower's single doorway faces east, oriented toward the rising sun.

When the Inca conquered the Colla in the fifteenth century, they did not destroy the chullpas. They added their own. The Inca-period towers are distinguishable by their stonework — perfectly fitted blocks without mortar, surfaces smoothed to a precision that rivals Cusco's finest walls. The largest, the Chullpa del Lagarto, is the tallest structure on the site.

The result is a cemetery where two cultures' funerary traditions coexist on the same hilltop. The older Colla towers, built with rectangular blocks and a distinctive construction style, stand beside Inca additions that refined the form without altering its meaning. Both cultures understood the same thing: the dead remain. They require housing. They face the sun.

Part of Sillustani.

The Colla began building funerary towers here in the 13th century. The Inca added their own after conquering the Colla in the 15th century. The complex comprises 91 towers of varying style and preservation.

The Colla people chose this hilltop above Lake Umayo as their most sacred burial ground. The peninsula's position — surrounded on three sides by water, open to the sky — created a geography appropriate for those who had passed between states of being. The Inca, after conquering the Colla, recognised the site's significance and added towers of their own rather than destroying what they found.

Colla funerary construction (13th century), Inca additions and refinement (15th century), colonial-era looting, present-day archaeological monument. The site represents one of the few places where Colla and Inca cultural expressions coexist without one having erased the other.

Sillustani is a city for the dead built between lake and sky, where ninety-one towers raise the departed above the ground in a gesture of continued presence rather than farewell.

The hilltop setting establishes the thinness before any individual tower is examined. The peninsula is surrounded on three sides by Lake Umayo, a body of water sacred to the Altiplano peoples. The sky above the Puno plateau is immense, and at 3,800 metres the air has a clarity that makes distance deceptive. The towers stand between these two elements — lake below, sky above — in a space that is neither land nor water nor air but something of all three.

The chullpas' upward orientation is the key gesture. Where most funerary traditions descend — into earth, into crypts, into the ground — the Colla and Inca built upward. The dead are not lowered but raised. They are not concealed but presented, standing in towers that face the sunrise. This inversion of the usual relationship between death and direction produces a landscape where the boundary between the living and the dead is not a grave's surface but a tower's wall — vertical, visible, and addressed to the sun.

The fetal burial position adds a temporal dimension. The dead were placed in the posture of the unborn — curled, contained, positioned for emergence. Whether this represented a belief in literal rebirth or a cosmological statement about the relationship between endings and beginnings is not documented. What is documented is the position itself, repeated across ninety-one towers over two centuries of construction.

An unfinished chullpa with its construction ramp still intact stands among the completed towers. The ramp shows how stones were moved upward during construction and reveals the point at which building stopped — for reasons unknown. The presence of this unfinished structure among the finished ones adds a dimension of incompleteness to the site: even among the dead, something was left undone.

Cemetery for the Colla elite, later adopted by the Inca for high-status burials. The hilltop position above Lake Umayo was chosen for its liminal geography — surrounded by water, exposed to sky, oriented toward the sunrise.

Colla construction from the 13th century; Inca additions in the 15th century; colonial-era looting of burial contents; present-day archaeological site with visitor facilities.

Elite burial in above-ground towers, with fetal-position interment, east-facing doorways, and accompanying offerings. The dead were understood to remain present and powerful.

Burial of elite families in fetal position with food, offerings, and personal possessions inside sealed chullpas. East-facing doorways ensured daily solar contact. Ritual visitation and periodic offerings maintained the relationship between living and dead. The construction of new towers was itself a ceremonial act — the unfinished chullpa with its ramp demonstrates that building was still occurring when construction ceased.

No active ceremonial use. Information boards provide educational context. Guided tours are available from Puno.

Walk among the towers as you would walk through a cemetery — with the awareness that these structures housed real people whose community believed they had not entirely departed. Examine the east-facing doorways and consider that each was oriented to receive the sunrise. Let the lake view add its own meaning.

A windswept hilltop walk among ninety-one funerary towers of varying size and preservation, overlooking Lake Umayo. The atmosphere is powerful and the silence, between gusts of wind, is complete.

Arrive at the site entrance and walk up the gentle slope to the hilltop. The landscape opens immediately — Lake Umayo below, the Altiplano extending in all directions, the sky taking up more than half the visual field. The first towers appear: smaller, older Colla constructions with their rectangular stone blocks and rough-fitted walls. Some are intact, others reduced to foundations.

As you walk deeper into the complex, the towers become larger and more refined. The Inca-period chullpas are unmistakable — their blocks perfectly fitted, their surfaces smooth, their overall form more deliberately finished than their Colla predecessors. The Chullpa del Lagarto, the tallest, stands among these later constructions.

Information boards are placed throughout the site, providing context for each group of towers. A guide, while optional, opens the historical dimensions that the boards compress. The unfinished chullpa with its visible construction ramp is among the most evocative structures — a project that stopped mid-work, its ramp still angled against the tower's side, the stones that should have completed it lying where they were left.

The site rewards slow walking. The towers' varying heights, construction techniques, and states of preservation create a landscape of accumulated time. The wind is nearly constant. The quiet between gusts is absolute. Lake Umayo reflects the towers and the sky. The overall impression is of a place where the relationship between the dead and the living was maintained not through ceremony alone but through architecture — through the sustained act of building houses for those who had not entirely departed.

Enter and walk broadly before focusing on individual towers. Allow the setting — lake, sky, wind — to register before examining stonework details. Visit both Colla and Inca towers to appreciate the stylistic difference. Find the east-facing doorways and note their orientation. The unfinished chullpa with its ramp is worth seeking out. Plan 1-2 hours.

Sillustani offers an encounter with a different understanding of death — one in which the dead are not buried but elevated, not hidden but presented to the sun, not separated from the living but housed nearby in towers that declare their continued authority.

Archaeologists recognise Sillustani as the finest example of the Altiplano chullpa tradition. The complex demonstrates continuity of ancestor worship from the Colla through the Inca period, with clearly distinguishable construction techniques marking each culture's contribution. The Qulla/Colla are increasingly understood as Puquina-speaking rather than Aymara, with implications for tracing their broader cultural connections. The east-facing doorways and fetal burial positions reflect an Andean cosmology of death-as-rebirth.

In Aymara and Quechua understanding, the ancestors at Sillustani are not gone but present in the landscape. The towers are their homes. The relationship between the living and these ancestors requires maintenance. Even if formal rituals have lapsed, the respect owed to the site persists in community memory and in the fact that Sillustani is still known, still visited, still spoken of as a place where the dead reside.

Some writers have proposed that the chullpas functioned as energy collectors or resonance chambers. These interpretations are speculative and not supported by mainstream archaeology, which consistently identifies the towers as funerary structures. The site's atmospheric quality may, however, contribute to such interpretations — the combination of wind, lake, sky, and stone towers produces an environment that invites metaphysical speculation.

The full social structure of the Colla elite buried at Sillustani is poorly understood. The unfinished chullpa with its construction ramp raises the question of why building stopped — conquest, resource shortage, or other factors. The ritual relationship between the chullpas and Lake Umayo, including any ceremonial use of the lake, is not well documented.

Sillustani is a cemetery. The appropriate posture is the respect owed to the dead, regardless of the centuries that separate you from them.

The ninety-one towers at Sillustani are funerary structures. While their contents have largely been removed through looting and excavation, their purpose remains. Walk through the complex with the quiet respect that any burial ground deserves. The towers' architectural interest — their stonework, their engineering — should not obscure their fundamental function: these were houses for people who died.
