Casa Blanca, El Salvador

Casa Blanca is a pre-Columbian Maya archeological site in the Chalchuapa archaeological zone in the department of Santa Ana, El Salvador. Its name comes from the coffee plantation that operated in the current archeological park. Archeological investigations show that the first occupation of this area started from Late Preclassic period (500 BC – AD 250). Later, in the first century AD, the large platform where most of the site's structures were built and other structures were constructed as an extension of the original ceremonial center located in the archeological site of El Trapiche (es).

It was abandoned after the end of the period, and reoccupied at the end of the early Classic period (AD 250 – 900) after the eruption of the Lake Ilopango caldera (dated between the 4th and 6th centuries AD). The occupation continued into the Late Classic Period (AD 600 – 900). It was occasionally used for burials and pilgrimages into the Postclassic period (AD 900 – 1520).
