This can be seen from the three-window shrine. The original three-window shrine originally had five windows, and the windows on both ends were later blocked. From the photo below, it can be seen that the windows are blocked very rough, with large gaps exposed, and the stones used to block the two windows are different. It is obviously taken from other formed stones. This is not the exact architectural style of Inca engineers, but probably the Inca people's original stone building.
