It is located east of the Calzada de los Muertos. Among its structures are the Substructure of Group 17, also known as Temple of Tlaloc, and Structure 1G, on whose façade mural painting has been found.

Geometric figures in the shape of a chessboard: The mural consists of small red squares placed in the shape of an X on a white background, forming two crosses, one in front of the other in a horizontal strip. These motifs are delimited by three vertical stripes in green, yellow and red, a design that is repeated at regular intervals along the lower molding of the architectural board.
