Ciudad Perdida (Spanish for "Lost City") is the archaeological site of an ancient city in Colombia's Sierra Nevada. It is believed to have been founded about 800 CE, some 650 years earlier than Machu Picchu. This location is also known as Teyuna and Buritaca.
Ciudad Perdida consists of a series of 169 terraces carved into the mountainside, a net of tiled roads and several small circular plazas. The entrance can only be accessed by a climb up some 1,200 stone steps through dense jungle.
