Xlapak is about 6 km (3.5 mi.) e. of Sayil. Xlapak (shla-PAHK) means “old walls” in Maya. The notable structure at this small site on the south side of the road is the partially restored Palace of Xlapak, which is decorated with Chac masks, some flaunting curled noses. The restored portions are lighter in tone than the weathered, unrestored sections.
