Group F is a residential group to the north of the defensive system on the mainland and may also date to the Terminal Classic period. Zacpeten's Late Postclassic period occupation is concentrated in four of the five groups on the peninsula. Groups D and E were elite residential groups while Groups A and C are dominated by ceremonial buildings style similar to that of Mayapan, and associated with the Kowoj. This style consists of a temple assemblage with raised shrines that lie a right angles to a western facing temple rather than facing into it. This specific variant appears at central Petén Basin sites including Topoxte and Muralla de Leon.
