Hotel del Salto, Tequendama Falls, 30 km from Bogotá, Colombia
Carlos Arturo Tapias, 1923
The hotel was abandoned when the waterfall became toxic. The site became a departure point for suicide victims, and their memories haunted the hotel. Supposedly purified of evil spirits, now a museum of biodiversity.
