The Name Guatapé: What the Reservoir Buried, and What Survived

Millions of people visit Guatapé every year. They come for La Piedra del Peñol, the monolithic rock that rises from the surrounding landscape, and for the reservoir: 62,000 hectares of green water threading through the mountains of eastern Antioquia. Almost none of them know that the reservoir is itself the site of a second displacement. The first began with Spanish conquest. The name of the town is the thread that connects both.

A Name Before a Town

The word "Guatapé" predates the colonial settlement. In Tahamí oral tradition and in accounts of early colonial contact, Guatapé was the name of an indigenous leader, a cacique, of the Tahamí people. The Tahamí occupied the mountainous valleys of eastern Antioquia, farming cold-climate crops along the rivers that descended from the central cordillera. The name of their leader, or the designation they gave to their territory, was what Spanish cartographers ultimately recorded as "Guatapé."

The Tahamí are classified within the broader Carib linguistic family in some anthropological accounts, though the classification of Antioquian indigenous groups remains a matter of ongoing scholarly discussion. What is documented is their presence in the eastern Antioquian highlands, their resistance to Spanish encroachment, and the eventual collapse of their political autonomy under colonial pressure. They were not a marginal group. They were settled people with agricultural systems, political structures, and territorial names that outlasted them as a distinct political body.

Conquest and the Resguardo

The Tahamí resisted the initial Spanish incursions. Their territory was not easily accessed, and they were not easily subdued. The combination of Spanish military force, epidemic disease, and the systematic dismantling of indigenous political structures eventually prevailed. By the 18th century, the surviving Tahamí population was reorganized under a colonial resguardo: San Antonio del Remolino de El Peñol, established formally in 1714.

The resguardo was the colonial mechanism for concentrating and controlling indigenous populations while nominally protecting them from complete expropriation. For the Tahamí, it represented both survival and confinement: a recognized space, but not their original territory on their own terms. The colonial state acknowledged their existence while terminating their autonomy.

From this resguardo, the towns of El Peñol and Guatapé developed over the following two centuries. The indigenous roots of the settlement became embedded in local surnames and in the name of the municipality itself, while the communities that formed were increasingly mestizo in composition. The Tahamí did not disappear from history in one moment. They were absorbed, dispersed, and documented less and less as the colonial record shifted its attention to the towns built over their territory.

The Second Displacement

The first displacement was the conquest. The second came in the 20th century, through a project of national development.

Between 1970 and 1972, the Peñol-Guatapé hydroelectric dam was constructed by Interconexión Eléctrica S.A. (ISA). The dam required flooding the Río Nare valley. More than 6,200 hectares of farmland, roads, forests, and the original town of El Peñol were submerged. Approximately 3,000 people were displaced, many from families that had worked the same land for generations, including descendants of the original Tahamí resguardo.

The residents were relocated to a new town, also called El Peñol, built on higher ground. They carried belongings and rebuilt. But the physical landscape of their community, the streets, the church, the agricultural land that had sustained families across centuries, went underwater. The church steeple of the original El Peñol is occasionally visible above the waterline when reservoir levels drop. It is the most legible marker of what the water holds.

The decision to flood the valley was made at the level of the national energy grid. The people living there had no meaningful participation in that decision. Compensation was paid, but the process of relocation was managed by the state and ISA on their terms and timeline. The community's relationship to that land, including any remaining connection to the resguardo territory established in 1714, was severed by decree and by water.

What the Reservoir Is

The Embalse Peñol-Guatapé is now one of the most photographed landscapes in Colombia. It provides approximately 30 percent of the country's hydroelectric generation. Tourists from Medellín come by the busload on weekends. Boat tours cross the water above where the town used to stand.

The reservoir is simultaneously an engineering achievement, a significant national energy asset, and a site of accumulated displacement. These things coexist without resolution. Framing it only as a natural landmark, as most tourism materials do, requires ignoring the town beneath the waterline and the colonial history beneath that. Neither layer cancels the other. Both are present in the same geography.

What Survived

The name survived. "Guatapé" remained on the maps after the conquest erased the political structure of the Tahamí. It remained on the maps after the dam erased the physical town of El Peñol. Today it names a municipality, a reservoir, and a tourism destination. It also names a cacique who inhabited these mountains long before either event.

Local surnames in the Guatapé and El Peñol area still carry traces of Tahamí lineage. The oral tradition connecting the name to the indigenous leader has been maintained by local historians and community memory, even where formal documentation is incomplete or contested. The distinction between what is documented and what is remembered matters here: both are legitimate forms of knowledge about a people whose written record was largely produced by those who colonized them.

The colored panels on the buildings of Guatapé, the zócalos, are a form of this same continuity. A community covering its walls with images of its own identity, asserting presence in a place that has twice seen the erasure of whoever came before. The zócalos are typically read as folk art or as tourist attraction. They are also a record of people insisting on being seen.

The reservoir looks like a natural lake. The colonial record looks like settled history. The question worth holding while visiting Guatapé is what those appearances are built on top of, and what the word "Guatapé" was before it became a destination.
