Xlapak means "old walls" in Maya.
Xlapak is a very small site that is very close to Labná -- so close, in fact, that it may have actually been part of Labná. Structure 1 is the only building on the site that is in good enough condition to be of interest to anyone but an archaeologist. It is an interesting example of the Classic Puuc Mosaic Style and dates to approximately A.D. 830 to 1000. According to Joyce Kelly, Structure 1 was restored by the Mexican government in the late 1960s.
