There the symmetries end, since, while in the third kancha there is a chamber beside the large reception room, in the first there is an empty space in whose northeast end appears a little room. The reception room of the third kancha has a patio behind it as long as it is and that of the second kancha has a smaller one. North of this last one there is a large empty space that stretches to the back of the large reception room of the first kancha, where next to the outcrops of rocks we also find remains of complementary structures. It is difficult to attribute functions to the palace with three portals. Possibly it was a set of buildings in which consultations were taken care of or audiences were carried out. We could assume that some of the chambers were rooms, although all this is speculative. In the excavations Alfredo Valencia made in 1974 he did not find sufficient evidence to assign specific uses, given that the potsherds and stone hammers that he found were not only common in the site but also, in addition, had been disturbed in 1956 by reconstructors who worked in Machu Picchu by order of a Cuzco development organization. pag. 1 - 2
