Overview
Ciudad Perdida (Spanish for "lost city"; also known as Teyuna and Buritaca-200) is the archaeological site of an ancient city in the Sierra Nevada de Santa Marta of Colombia, within the jurisdiction of the city of Santa Marta. This city is believed to have been founded about 800 CE. If so, Ciudad Perdida predates Machu Picchu by about 650 years.
Ciudad Perdida consists of a series of 169 terraces carved into the mountainside, a network of tiled roads, and several small circular plazas. The entrance can be accessed only by climbing up 1,200 stone steps through dense jungle.
Modern discovery
Ciudad Perdida was discovered in 1972 by Los Sepúlvedas, a group of local treasure looters. They made one of the greatest archaeological discoveries in modern times.
Los Sepúlvedas were a small family of looters living in Colombia. The family often went hunting in the forests, and one day they shot a wild turkey. While retrieving the turkey, they noticed it had fallen on a series of stone steps rising up the mountainside. They climbed up the stone steps and discovered an abandoned city, which they named "Green Hell" or "Wide Set". After the murder of one of the Sepúlveda sons at the site of Ciudad Perdida, fights broke out among the looters.
