Incas used a mix of yucay limestone, green sacsahuaman diorite porphyry, and black andesite to make their stone for their buildings. Roofs made from grasses or reeds placed on poles made of wood or cane. Stone was shaped with harder stones and bronze tools and were pounded not cut. Buildings survived 500 years of earthquakes. Buildings with high honor were sheeted with gold.
