The turquoise waters of the Peñol-Guatapé Reservoir are among the most photographed landscapes in Colombia. Tourists climb the rock, cruise the lake, and photograph the colorful zócalos of Guatapé's town center. What most visitors don't realize is that beneath those turquoise waters lies a drowned valley, a demolished town, and a community displacement story that redefined Eastern Antioquia.
Before the Flood
Before the 1970s, the valley between El Peñol and Guatapé was agricultural land — small farms, a church, a plaza, and the rhythms of rural Antioqueño life that had persisted for over 200 years. El Peñol, founded in 1714, was a modest town whose inhabitants were primarily peasant farmers. Guatapé, on the adjoining hillside, was similarly rural, known for small-scale agriculture and the massive granite monolith (El Peñón) that rose improbably from the landscape.
In the early 1960s, Empresas Públicas de Medellín (EPM) identified the valley as the optimal site for a major hydroelectric project. The dam would flood the valley, create an artificial reservoir, and generate electricity for Medellín's rapidly growing industrial economy. The technical logic was sound. The human cost was enormous.
The Displacement
The community of El Peñol organized massively against the project. In 1969, after years of protest, a document called the Contrato Maestro was signed between EPM and the municipality, containing 95 clauses intended to mitigate the impact of resettlement. A new town — El Nuevo Peñol — was constructed approximately 57 kilometers away. Houses were built, streets were laid, a new church was erected.
But a new town is not a community. The displacement shattered generational ties to specific plots of land, disrupted agricultural livelihoods, and forced families into an unfamiliar economic model. The flooding itself, which accelerated in the 1970s, was physically dramatic: buildings were demolished before the waters rose, but at the request of residents, a stone pillar with a metal cross was erected on the spot where the old church had stood — a marker visible above the waterline during low-reservoir periods.
Guatapé's urban center survived — the town sits higher than the reservoir level — but its rural areas were partially flooded, altering the municipality's geography and economy permanently. The town that faces the reservoir today is fundamentally different from the agricultural community that existed before the dam.
The Reinvention
What happened next is one of Colombia's most striking examples of economic reinvention. The reservoir, which had destroyed agricultural communities, created an entirely new economic asset: a scenic, island-studded lake surrounded by mountains, with calm waters perfect for boating, fishing, and watersports. Gradually, the land around the reservoir became some of the most valuable real estate in Antioquia.
Finca construction along the reservoir shoreline accelerated through the 1980s and 1990s. Medellín's wealthy families — including, notoriously, Pablo Escobar, whose lakeside estate La Manuela was bombed by the vigilante group Los Pepes in 1993 — recognized the area's potential as a weekend retreat. Today, lakefront finca properties command some of the highest nightly rates in Colombia's rental market.
Guatapé's town center underwent its own reinvention. The zócalos — decorative cement relief panels along the lower walls of buildings — became the town's signature aesthetic, transforming Guatapé into one of Colombia's most visually distinctive destinations. The tradition reportedly began in 1919 with resident José María Parra Jiménez, who started depicting daily scenes in relief on his house's corridor. The art spread from house to street to plaza until it became an identity.
Guatapé did not become Colombia's most Instagrammed finca destination by accident. It was built, flooded, displaced, and rebuilt — and the beauty tourists photograph today is inseparable from the loss underneath.
Visiting with Context
Understanding Guatapé's history enriches rather than diminishes the experience. Visitors can take boat tours that pass over the flooded valley, visit the Parque Temático Réplica del Viejo Peñol (a reconstructed miniature of the original town), and on clear days at low water, glimpse the cross that marks the old church's location.
The people of El Peñol, notably, built their new town facing away from the reservoir. Not looking at it, they say, was the way to heal. Guatapé, by contrast, faces the water directly — a physical expression of the two communities' different relationships to the same traumatic event.
For the finca traveler, this context matters. The lakefront property you're renting exists because a valley was flooded and a community was displaced. The beauty is real. The history is real. Both can be held simultaneously, and the most meaningful finca stays in Guatapé are the ones that acknowledge this.
