The Eastern Acropolis as seen in 1943
Ruppert & Denison 1943: detail from Plate 68
It is interesting to note that Structure II faces both east and west and Structure IV faces both north and south, but Structure I turns its back on the courtyard and faces only to the south.

The central plaza group is defined on the east by structure VIII and on the west by Structure X. Structure IX is by far the highest structure at Becan, but it is little more than an impressive mound of rubble [Structure IX has since been restored].
Ruppert wrote in 1943: "Structure IX, lying northwest of Structure VIII and rising 32 m. above the terrace, is the highest pyramid in the city. It, with a long mound to the west, bounds the north side of the Central Plaza; Structure X, the west; and Structure VIII, the east. A stairway, now in ruins, on the south side of Structure IX rose at an angle of approximately 51°. The acclivity at the top of the pyramid seems to indicate a superstructure, of which, however, no walls are visible. Stela 3 stands at the south base of this pyramid.

The west plaza includes the back of Structure X to the east (far right), the ballcourt (labled XI) and by a series of poorly preserved structures to on the west side collectively known as Structure XIII. Potter remarks that this group is scarcely better known today than it was at the time of Ruppert's report in 1943.
