Ingapirca

Ingapirca (Kichwa: Inka Pirka, "Inca wall") is a town in Cañar Province, Ecuador, and the name of the older Inca ruins and archeological site nearby.

These are the largest known Inca ruins in Ecuador. The most significant building is the Temple of the Sun, an elliptically shaped building constructed around a large rock. The building is constructed in the Inca way without mortar, as are most of the structures in the complex. The stones were carefully chiseled and fashioned to fit together perfectly. The Temple of the Sun was positioned so that on the solstices, at exactly the right time of day, sunlight would fall through the center of the doorway of the small chamber at the top of the temple. Most of this chamber has fallen down.
