A number of buildings and ruins were made using Polygonal laying, and also reveal elements of Plasticine technology. The quality of stone processing and the precision of the fitting of the building blocks cast doubt on the authorship of the Incas, who were in the Bronze Age at the time of the conquistadors' arrival. According to the Spanish, the Incas themselves denied their involvement in the ancient buildings, calling them the work of some ancient gods. The technological level also did not allow the Incas to carry out construction work of such quality - the bronze tools they had were not suitable for processing a fairly hard variety of basalt. In addition, the Incas did not know the wheel and did not know how to use pack animals to transport goods.
