The site reached its housing peak probably in the
early classical period (250-600 AD). The first settlers built houses on platforms, although the organic materials used have not been preserved over the centuries. Between the years 200 and 1200 AD. the inhabitants of the site worked as fishermen and in salt extraction. In a later period the site gained importance because immigrants arrived from the interior of the
Yucatan Peninsula, approximately between 1300 and 1500 AD. The structures that can currently be seen date from then. Within the coastal commercial network El Rey was one of the ports on the Caribbean coast. Other important ports in the south were
Xcaret,
Xelha,
Tulum, and
Muyil. After the arrival of the Spaniards in the sixteenth century, the site was abandoned by the Mayans. == Archaeology ==
