Guaytán is an archaeological site of the Maya civilization in the municipality of San Agustín Acasaguastlán, in the department of El Progreso, in Guatemala.
[14] The crypts were built with large slabs of stone to form chambers that measured approximately 2 metres (6.6 ft) high.
Guaytán was one of two sites (the other being La Vega de Cobán, in Zacapa) that controlled most of the trade passing along the Motagua River.
In the Early Classic, the city underwent a population explosion and there was contact with the great metropolis of Teotihuacan, in the distant Valley of Mexico.
By the Late Classic, contacts extended to the Petén lowlands, the Yucatán Peninsula, and the western portions of Honduras and El Salvador.
