Ceremonial arches are a common feature throughout the Puuc, and this example is the most elaborate of all. The decoration of this facade, in contrast to the other side, is entirely geometric. The projecting roof combs above the cornice have been reconstructed and were probably taller and decorated with figures modelled in stucco over a stone armature. These figures were attached to stone tenons in the roof comb, which were omitted in the restoration.
The arch stands at one corner of an irregular, almost trapezoidal courtyard atop a terrace reached by a short flight of stairs, buried in Stephens' time, and excavated and repaired by the Mexican government about 35 years ago.
