Structure 31 is an unusual residential building since it is typically Mayan-Chontal. It has large interior spaces with a frontal portico, and its roof was made of palm fronds, while Structure 32 is a small masonry temple. It is considered that the former structure was the house of the "Halach Uinic" of Cozumel and the latter the private "chapel" of the liege. Both structures date from the Post Classic period (1200-1650 a.d.).
