Inca temples were typically built using large stones, often limestone, granite or porphyry. The stones were carefully cut and fitted together without the use of mortar or cement, creating incredibly strong structures. The walls were often decorated with intricate carvings and sculptures depicting religious symbols, animals, and plants. The roofs of the temples were typically made of thatched straw or reeds, but some temples also had roofs made of stone or adobe bricks.
