The San Agustin archaeological park in Colombia includes a wide variety of stone sculptures, mostly carved between AD 100 and 1200. In the park are an amazing array of separate stone sculptures, in the shapes of animals and warriors and human faces, some mythical, some realistic. They are carved out of volcanic rock - some are over 4 meters tall and weigh several tons. The site, excavated by K. Th. Preuss during the 1940s, has been declared a World Heritage Site.
