The Temple sector is built out of cut and fitted stones in contrast to the other two sectors of the Temple Hill, which are made out of fieldstones. It is accessed by a stairway that ends on a terrace with a half-finished gate and the Enclosure of the Ten Niches, a one-room building. Behind them is an open space which hosts the Platform of the Carved Seat and two unfinished monumental walls. The main structure of the whole sector is the Sun Temple, an uncompleted building which features the Wall of the Six Monoliths. The Middle and Funerary sectors have several rectangular buildings, some of them with two floors; also, several fountains are in the Middle sector.
