The pre-Columbian monumental site of Pachacamac (Peru) covers an area of almost 600 hectares. It lies at the mouth of the Lurín
River, close to the Pacific shore, some 30 km south of Lima and is considered to be one of the most important ancient settlements
of the Central Andes, on a par with Machu Picchu, Tiahuanaco, Chavín de Huantar, Chan Chan and the Nazca Lines.The Ychsma Project,
directed by Dr Peter Eeckhout, has carried out archaeological field research at Pachacamac since 1999.
