Tikal: Plaza of the Seven Temples, Str. 5D-91 [January 7, 1998]
Harrison describes this Janus-facing building as a passage structure, "...serving the function of passage from a public space into a ceremonial space. The most prominent example is 5D-91 on the south side of the Plaza of the Seven Temples. A formal Ceremonial stair is visible on the south side of this major palace."
