It is a basal platform of reduced dimensions. It consists of four bodies and it is located to the east of the Tower. In him two small cylindrical altars are appreciated, one at the foot of the stairway and another before passing to the sanctuary of the superior part. The first body lacks well-cut ashlars, as is common in most of the construction; they were probably removed in the last decades of occupation of the site, and it is worth noting the presence of alfardas, a common element in the Río Bec and Chenes architectures.
