The Pambamarca Fortress Complex consists of the ruins of a large number of pukaras and other constructions of the Inca Empire. The fortresses were constructed in the late 15th century by the Incas to overcome the opposition of the people of the Cayambe chiefdom to the expansion of the Incas in the Andes highlands of present-day northern Ecuador. The Pambamarca fortresses are located in Cayambe Canton in Pichincha Province about 32 kilometres (20 mi) in a straight-line distance northeast of the city of Quito.

The Inca-Caranqui archaeological site is located in the village of Caranqui on the southern outskirts of the city of Ibarra, Ecuador. The ruin is located in a fertile valley at an elevation of 2,299 metres (7,543 ft). The region around Caranqui, extending into the present day country of Colombia, was the northernmost outpost of the Inca Empire and the last to be added to the empire before the Spanish conquest of 1533. The archaeological region is also called the Pais Caranqui.
