Leon states Vilcas was a principal and very important place in the Incan kingdom. "There were beautiful buildings and a temple with great wealth." The natives, "burned the most important of them and removed the sacred women and treasures so that the Spaniards could not take advantage of them. Two royal highways, if not three, lead from this [place] that they call Vilcas."[4]: 287
