It is impossible to say positively whether this was merely a wall which guarded the entrance to the Cuzco Valley, or whether it was an aqueduct that once carried water to the city of Piquillacta. Photo by Hiram Binglham AN ARCHITECTURAL PUZZLE: RUMI CCOLCA A nearer view of Rumi Ccolca shows the junction of two entirely 'different kinds of stonework. The original wall is of rough stones laid in mud, but the gateway is lined with cut stones fitted together without mortar after the best Inca style. It may be possible that a later race cut a gate through the ancient aqueduct and lined it in their own fashion with their best stonework.
