House with Columns (Casa de las columnas)

This is the largest residential complex, also known as the "Great Palace," situated on an L-shaped platform. The name "Great Palace" was given mainly because of its palace-type building with two rooms and two others connected together on its western side. The main entrance is located on the southern side and consists of four columns. Inside, there are six columns supporting the roof of the large hall, with a covered sanctuary in the center. The building's windows still retain hinges, which were likely used to attach curtains.
