San Agustin, Colombia
In Southern Colombia, there is a city called, San Agustin, which is known for an enigmatic civilization that once lived there. As most ancient civilizations have done, the Agustinians left behind ruins. Except their ruins weren't in the form of pyramids or temples but hundreds upon hundreds of intricately carved stone heads. These large stone heads are believed to have served as gravestones marking burial plots, but sometimes represented idols as well.
