 Archaeology demonstrates that San Andrés had strong contacts with Copán and the Guatemalan Highlands, and received goods from such distant places as the present territories of Petén and Belize.San Andrés collapsed as a political center towards end of the 9th century.The last evidence of pre-Hispanic activity in the site was between the years 900 and 1200 as a residential site that consists of a final layer with fragments of censers and ceramics painted with scenes of sacrifice in Mixteca-Puebla style, which belong to a new cultural phase, named "Guazapa", related to the pre-Hispanic city of Cihuatán.
