Nestled in the heart of the vast Andean ranges of Cauca, Colombia, the Tierradentro ruins were once hidden from the outside world by decades of civil war.
Little is known about Tierradentro, meaning “inside earth,” but the UNESCO World Heritage Site is unlike anywhere else in the world. The ruins are made up of a cluster of 162 ancient burial chambers—called hypogea—that are believed to date back to between 600 and 900, before Spanish colonization.
