"The two end towers of Structure I are round cornered, are stepped, and had steep, nonfunctional, front staircases. The top of each tower once supported a small false temple. These ornamental towers appear to be small nonfunctional copies of pyramid-temple structures at Tikal, roughly 140 km. south of Chicanna, and also built during the middle of the Late Classic period. The original appearance of Structure I is verified by a graffito incised on the wall plaster of Room 2, Structure II, across the plaza; it depicts this building in its original state."
