lower areas have diagonal lines of various colors such as black, green, ochre and red with some lines in white. Some areas have red stars. Mural work on Buildings 3.2 and 4 are similar in their use of multicolored diagonal bands with stars painted in some areas. Building D Building D is located on the south side of the Pyramid of the Nine Stories. It consists of pyramid like levels of talud-tablero topped with three moldings on the east and two on the west. The levels are rectangles with rounded corners, painted black on three sides with the east side in orange. The murals on the tableros have no figures on them and the cornices are painted black. The building was constructed over an area, whose interior is covered with stone pieces with red, ochre and green paint over black. This area was filled in because later constructions around it were putting pressure on it and it was in danger of collapse. Building I Building I was unearthed during a brief period of six months at the beginning of the second round of excavation, mostly by Eduardo Matos Moctezuma and Pablo López Valdéz. This building is located on a platform affixed onto the southwest side of the pyramid. It has four means of access, common to momoztli and contained three burials. The ceramics found with these are similar to those found at the Altar of the Sculpted Skulls, dating the structure as late into Cholula's pre Hispanic period. These two finds show that while the pyramid was in process of abandonment, it had not lost its ritual character. Building F Building F dates from the next to last building phase of the pyramid, between 500 and 700 AD. It is a stone stairway, consisting of three levels with large taluds facing west. The tableros are decorated with a motif that looks like a woven palm mat. This effect was created by sculpting stones, then placing them like a mosaic. For this reason, the structure is also referred to as the Piedra Laborada (Worked Stone) building. Using stone found from both the taluds and the tableros, the archeologists set about reconstructing this structure, using commercially made cement, leading to the structure being called the Tolteca pyramid, after the brand used. This pyramid has since been criticized for being overly reconstructed. The process yielded a large number of ceramics figurines and vessels,
