Ingapirca
Ingapirca is both the name of a town in Ecuador's Caar Province and the name of an earlier Inca ruins and archeological site nearby. These are Ecuador's largest known Inca ruins. The Temple of the Sun, an elliptically shaped structure built around a massive rock, is the most important structure.
A visit here will let you observe the legendary Inca stonework, which is known for its seemingly impenetrably tight joints. The Caari occupied this area long before the Incas came, and several of their original structures are on show. Both the Caari and the Incas are said to have revered the location.
Location: Cañar Province, Ecuador
