The northern side of the Great Acropolis court is closed by a Puuc-style building that has only recently been excavated. The low, C-shaped platform in front of its stairs is probably Postclassic in origin and is typical of late occupation of Classic sites, when squatters took over the abandoned cities and built low stone platforms in courtyards and plazas as foundations for dwellings. The vast, flat landscape of Campeche extends beyond the ruins. At the extreme left of the horizon, an outcrop covered with vegetation can be seen: this is the unexcavated ruin of a large complex nicknamed "La Vieja."
