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.[1] Tres Islas is situated on the west bank of the Pasión River in the municipality of Sayaxché in Guatemala's northern department of Petén.[3] 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.The arrangement of the stelae and altar precisely mimics the orientation and relationships of the E-Group astronomical complex at Uaxactun, suggesting that the monument group served a similar purpose.The image of the warrior is very similar to the portrait of Tikal king Yax Nuun Ayiin I as depicted on Stela 31 of that city.
