You need to hire a boat to take you to Topoxte Island on the Guatemalan Yaxha Lake. There are remains of many structures on the island, the largest of which belongs to the ceremonial center of the ancient city. Construction activities lasted here until the late Postclassic period, probably the mid-15th century. This suggests a population influx after the collapsed of the cities in the end of the Maya Classic period.
The stepped pyramid known as Building C is an example of the Postclassic architecture. The pyramid has a steep stairway ascending from the plaza in the ceremonial complex. It had temple building on top and associated was with human sacrifice. The architectural style similar is to that of Mayapan, suggesting strong ties to this important Postclassic city in the northern Yucatán Peninsula.
There are number of burial sites across the Topoxte Island. They date from different time periods. Some of the graves belong to children, but many have been identified as the remains of people between the ages 17 and 25, rarely older.
