The Spanish conquerors called the region Tierradentro for the mountain knots and deep canyons of its topography that generated the sensation of being closed in by mountains, being ‘inside the earth’. 

There is not much is known about the pre-Colombian civilization who created the burial chambers – only that the tombs were created around 700 A.D. and were rediscovered and excavated between 1930 and 1995. This UNESCO world cultural heritage is one of the largest pre-Colombian gravesites and contains underground shaft graves with black and red wall paintings.
