Tres Islas
Petén Department, Guatemala
Tres Islas (Spanish for "Three Islands") is a small pre-Columbian Maya archaeological site 20 kilometres (12 mi) north of Cancuen in Petén Department, northern Guatemala. The site has been dated to the Late Preclassic (c.400 BC - 250 AD) and Late Classic (c.600-900 AD) periods of Mesoamerican chronology. The main feature of the site is a group of three Maya stelae and an altar, arranged in a way that mimics an E-Group Maya astronomical complex. Tres Islas is one of only a few Maya cities that erected dated monuments in the Early Classic period (c. AD 250 - 600).
