ABSTRACT
The buildings of the Inca were built of undecorated stone blocks with trapezoidal doors and windows. Stones were fitted precisely together; in fact, many were carved in place, laid atop one another then shaped to fit. Incan architecture often incorporated natural stone outcroppings into buildings and other structures. Thrones were often carved from rocks already in place. Terraces, fountains, and artificial waterfalls were characteristic of Incan cities and ceremonial centers.
