Cusco, a city in the Peruvian Andes, was once capital of the Inca Empire, and is now known for its archaeological remains and Spanish colonial architecture. Plaza de Armas is the central square in the old city, with arcades, carved wooden balconies and Incan wall ruins. The baroque Santo Domingo Convent was built on top of the Incan Temple of the Sun (Qoricancha), and has archaeological remains of Inca stonework.
