Rivas District

A Chiriqui Period (AD 750-1500) archaeological site in the Perez Zeledon canton, San Jose province, Costa Rica, discovered in the 1980s by Robert Drolet. Excavations began in 1992 under Jeffrey Quilter of the Peabody Museum, Harvard University. Over six years, researchers identified residential areas with river cobble structures in circular patterns ranging from 10 to 30 metres in diameter with adjoining rectangular patios. Paths, causeways, plazas, and stairways were recorded throughout. Over 600,000 ceramic sherds were recovered, with 60% of rims decorated in the Buenos Aires Polychrome tradition, considered Chiriqui Period 'fiesta ware'.
