Puruchuco is a restored Inca-period Ychsma palace complex in the Ate district of eastern Lima, Peru, built in the 15th century as the residence of a regional curaca. The name comes from the Quechua puruchuku, meaning feathered helmet. Arturo Jimenez Borja excavated and restored the site between 1953 and 1960, opening it as one of the first on-site museums in Peru. The building consists of a U-shaped adobe compound around a central plaza, with painted walls in white, red, and yellow and a series of small storage cells along the rear wall. In 1999 a major rescue excavation in the adjacent cemetery zone known as Tupac Amaru recovered more than 2,200 mummy bundles ahead of urban expansion — one of the largest single Inca-period cemetery excavations on record.
The compound's exterior walls were restored to their original sloping inward batter, the adobe surfaces still bearing finger-trowel marks from the original masons.
