An important part of Inca plazas was the ushnu, a structure of religious and political significance. The ushnu usually took the form of a low stone pyramid, but its defining feature was that it provided a channel for liquid to be poured out in libation. Some scholars argue that the pyramid was optional, while others argue that the pyramid and the channel must be understood as one construction. Ushnus signified Inca imperial power both through the rituals performed on them and through their construction, which often required moving stones long distances across the empire. Here, Guaman Poma depicts an ushnu as the “trono y aciento del Ynga.”
