Its name is derived from the fragments of red paint that were found inside. Means small holes and alludes to its lime roofcomb. The structure is comprised of an antechamber, 3 rooms and has a sculptured hieroglyphic inscription in the main chamber. The fayade is smooth with 2 roofcombs which bring to mind the late Puuc style of the terminal Classic period. It must have had a religous/public use, since there is a Ball Court joined to its eastern side, with basreliefs in the Maya-Toltec style.
