Tequendama Falls Museum, Museum in San Antonio del Tequendama, Colombia

The Tequendama Falls Museum is a natural history museum inside a 1920s mansion on the cliff edge of Tequendama Falls in San Antonio del Tequendama, Colombia. The three-story building houses exhibition rooms with specimens, drawings, and panels about the wildlife and plants of the region around the Bogotá River.

The building was built in 1923 during the presidency of Pedro Nel Ospina as a private retreat in the mountains. From 1928 it served as a hotel for wealthy guests and remained open until the early 1990s, when it was abandoned.

The name Tequendama comes from the Chibcha language of the Muisca and means "he who precipitated downward". The house was built as a symbol of the joy and elegance of the elite of the 1920s, and was reached by train from Bogotá. Today the museum works to raise awareness of pollution in the Bogotá River and how to restore its ecosystem.

Access is along a winding mountain road about an hour southwest of Bogotá. The rooms are spread over several levels, so plan some time for the tour and wear sturdy shoes.

The name Tequendama comes from the Chibcha language of the Muisca and means "he who precipitated downward". The building was reached by train from Bogotá in its hotel years. The European Union gave €300,000 (about US$410,000) for the reconstruction and the adjacent grounds.
