History
The town was originally founded along the Negro-Nare River in 1714 by Fray Miguel de Castro y Rivadeneiro. The area was inhabited by the indigenous Tahamí people prior to the Spanish arrival and colonization of the area.

In 1971, Empresas Públicas de Medellín determined that more water and power was needed to support the rapidly growing city of Medellín, located approximately 50mi/30km to the west, and decided that the Negro-Nare River should be dammed at Guatape, flooding the Negro-Nare River valley in which El Peñol was located. The old town seized by eminent domain and a new town was built several miles west, disrupting the lives of several thousand residents who were then forced to move to the new town without recourse.

The new dam was completed and the valley flooded in 1978. The El Peñol-Guatapé Reservoir now sits over the former location of El Peñol. A cross now marks the location in the reservoir above the former parish of El Viejo Peñol that fronted the town plaza. Some rural parts of Guatape were also flooded and lost.

Climate
El Peñol has a subtropical highland climate (Köppen: Cfb) consistently warm temperatures and abundant rainfall.
