Quadrangular plaza of large dimensions, which is composed of galleries and temples formed by columns that supported large vaults. The buildings that stand out in this space are the Market, the Temple of the Sculpted Columns and the Temple of the Small Tables.

Palace of the Sculpted Columns: For its outstanding work of bas-reliefs in jambs and columns, it is one of the most important buildings on the east side of the Square of the Thousand Columns. Its architectural characteristics denote a civic-religious function. It has a front gallery and a series of interior bays.

Originally its three facades were decorated with geometric drawings, characters and masks of the narigudo god. In its interior there are walls of later constructive stages that close the space between the columns.
