Tres Islas

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).

Tres Islas is situated on the west bank of the Pasión River in the municipality of Sayaxché in Guatemala's northern department of Petén. It is approximately 20 kilometres (12 mi) west of the ruins of Machaquila and about the same distance north of Cancuén. It is about 20 kilometres (12 mi) south of Seibal.

The early presence of the Emblem glyph that was later associated with the Late Classic Cancuen-Machaquila kingdom indicates that Tres Islas was the Early Classic capital of the kingdom, with its functions as a capital city later being transferred to Cancuen. This period, represented by the sculpted monuments, was a time when the great metropolis of Teotihuacan in the Valley of Mexico was exerting a strong influence across the Maya region.
