This building, called the House of the Moon, closes the plaza on the Great Acropolis to the south. It is one of the site's best examples of pure Petén-style architecture. It is remarkable for its symmetry and particularly for its multiple doorways, separated by masonry pillasters that are uncommon in the Maya area. It has been suggested that the restoration of this building was somewhat excessive, and that may explain not only its pristine-looking modern appearance, but also some of its more unusual features.
