The History of Guatapé

The Name

Before Guatapé was a town with colorful buildings and a granite monolith drawing visitors from Medellín, it was a name. The name belonged to a Tahamí cacique — an indigenous leader of the people who inhabited the eastern Antioquian highlands long before Spanish boots touched this land. The Tahamí dominated a territory of cold rivers, mountain fog, and cultivated slopes. The valley that now fills the Embalse Peñol-Guatapé was their land. The name they gave it — or more precisely, the name their leader carried — is what the town still goes by today.

The Tahamí People

The Tahamí were one of the principal indigenous groups of Antioquia, occupying the mountainous terrain to the east and northeast of what is now Medellín. They were farmers and hunters, adapted to elevation. Their communities were spread across cold-climate valleys where they cultivated corn, potatoes, and other Andean crops alongside rivers that descended from the central cordillera.

They were not a passive people. When the Spanish arrived, the Tahamí resisted. Early expeditions into their territory faced sustained opposition. But resistance had limits against the combined force of Spanish weapons, disease, and the systematic dismantling of indigenous political structures. Over time, the Tahamí were pushed from their ancestral lands, reduced in number, and reorganized under colonial administration.

The Resguardo of 1714

By the early 18th century, the Tahamí who had survived were consolidated into a colonial administrative territory. In 1714, a resguardo — a designated indigenous reserve under Spanish law — was established: San Antonio del Remolino de El Peñol. The name is a mouthful and a layering: Spanish Christian naming on top of the existing geography. This was the formal location where the surviving Tahamí community was placed, where they tried to maintain continuity of culture and territory under conditions imposed by the colonial state.

The resguardo system was protection and constraint simultaneously — it acknowledged indigenous existence while confining and controlling it.

The Town That Grew

From the colonial resguardo, a town took shape. El Peñol grew as a community of mixed indigenous and mestizo settlers over the 18th and 19th centuries. The adjacent settlement that would become Guatapé developed separately, both towns sharing the same valley landscape: the rivers, the mountains, La Piedra — the granite monolith that both municipalities would later dispute.

By the 20th century, El Peñol was an established Antioquian town with a church, a plaza, and a community of several thousand people who had been on this land, in one form or another, for centuries.

The Dam

Between 1970 and 1972, construction of the Peñol-Guatapé hydroelectric dam transformed the valley permanently. The project was operated by Interconexíon Eléctrica S.A. (ISA), and it required flooding the Río Nare valley to create one of Colombia’s primary sources of hydroelectric power.

What that meant in practice: more than 6,200 hectares of valleys, roads, farmland, and the original town of El Peñol went underwater. Residents were relocated to a new settlement — the current El Peñol — built on higher ground nearby. They took what they could carry. Houses, crops, cemeteries, the physical infrastructure of community life — all of it went beneath the rising water.

The church steeple of the original El Peñol was the last thing to disappear. When reservoir levels drop low enough, it resurfaces — a cross above the water, marking what is underneath.

What Survived

The name survived. Guatapé remained on maps, in official records, in the surnames of families whose roots go back to the Tahamí cacique and his territory. The town rebuilt. The reservoir became an attraction. Visitors came for La Piedra and stayed for the colorful zócalos.

But the history underneath is rarely told at the waterfront restaurants or in the tour operator brochures. The reservoir that makes Guatapé visually striking — the blue water, the hundreds of peninsulas, the landscape that people photograph from the top of La Piedra — is the same reservoir that erased an indigenous-rooted colonial town and displaced its people for the second time in three centuries.

The name Guatapé is a cacique. The water is a dam. The town between them is what remained.

Visiting with This in Mind

None of this makes Guatapé a place to avoid. It makes it a place worth understanding more fully. When you stand at the top of La Piedra and look down at the reservoir, you’re looking at submerged history. When a boat tour passes over the old El Peñol, the guide may point to the church steeple. That’s the most visible part of what the water holds.

The zócalos — those painted relief panels on every building — are a form of cultural assertion too. A community that has been displaced twice, that has had its name taken and repurposed, covering its walls with images of who it is and where it comes from.
