Inca Architecture and Civil Engineering

Machu Picchu, Peru

For more than 300 years, the Inca ruled a large swathe of pre-Columbian South America, from Ecuador to Chile. Although their empire diminished with the Spanish conquest that began in 1533, their remarkable achievements in architecture and engineering live on, most notably in the iconic mountain citadel of Machu Picchu and the ancient capital of Cusco.
