The Ychsma Project, directed by Dr Peter Eeckhout of the Université Libre de Bruxelles (ULB), has carried out archaeological field research at Pachacamac, Peru since 1999.

This pre-Columbian monumental site 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.
