PUBLIC PYRAMIDAL BUILDING A1

The building was erected on the southeast periphery of the urban center, on a hillside with a succession of terraces. It is 82 m long, 52 m wide and 4.8 m high.

Using a central staircase the inhabitants reached the top of the building, where a large ceremonial hall was built, with other main and secondary rooms built later on.

They built with cut stones of different sizes, placed in irregular rows, with gray, brown and beige clay mortar. The deposits were made of smaller cut stones, mixed with gravel, earth and sand. In the later peri ods orthostats were placed in the retaining walls of the terraces.

This building is part of a complex located around a shared open space that has not yet been excavated.
