 Structure <unk> @-@ 43 is an unusual radial temple in the East Plaza , built over a pre @-@ existing twin pyramid complex . It is built into the end of the East Plaza Ballcourt and possessed four entry <unk> and three <unk> , the fourth ( south ) side was too close to the Central Acropolis for a stairway on that side . The building has a <unk> @-@ <unk> platform profile , modified from the original style found at <unk> . In fact , it has been suggested that the style of the building has closer <unk> with El <unk> and <unk> than with <unk> itself . The vertical <unk> panels are set between sloping <unk> panels and are decorated with paired disc symbols . Large flower symbols are set into the sloping <unk> panels , related to the Venus and star symbols used at <unk> . The roof of the structure was decorated with <unk> although only fragments now remain , showing a monstrous face , perhaps that of a jaguar , with another head emerging from the mouth . The second head possesses a <unk> tongue but is probably not that of a snake . The temple , and its associated ballcourt , probably date to the reign of <unk> <unk> Chaak or that of his son <unk> Chan K 'awiil I , in the later part of the 7th century .
