Two palaces investigated in Group E are architecturally quite different from the palaces in Groups C and D. A notable feature is that their doors possess projecting corners. The western structure has a vaulted room with a central bench and also a cross-shaped exterior bench, the walls of the structure still stand high. The north structure's walls stand high and its western room had been divided in two by the placement of vertical stone slabs. This north structure did not possess any interior benches. It may be that the different architectural styles of Group E and the other main groups at Motul de San José result from their association with different lineages, each with its own style.
