Pambamarca Fortress Complex

The Pambamarca Fortress Complex consists of the ruins of a large number of pukaras (hilltop forts) 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. In 1998, Pambamarca was placed on the tentative List of UNESCO World Heritage Sites.
