Ceremonial architecture outside the Zacpeten area follows a very different pattern. For example, Late Postclassic Itzá ceremonial groups do not appear to include formal temples. The residences at Zacpeten are tandem-shaped structures standing in patio groups. Tandem residences include a front room and back room and the former has a plastered and occasionally painted surface while the latter has an earthen floor. Household production activities are concentrated in the back room, while socializing and ritual performances were focused upon the front room.
