A large palace complex at the south end of the site, named by the Spanish for the comb-like roof ornamentation that resembles a dovecote. The roof crest — a long stone screen rising above the actual roofline, pierced with triangular and trapezoidal openings — is among the most elaborate surviving examples of this Maya architectural element. The palace itself is largely unrestored; the overgrown state gives it a different atmosphere from the more excavated central monuments.
