Quispiguanca

The ruins of the estate are located in the northern part of the present-day town of Urubamba, Peru at an elevation of 2,910 metres (9,550 ft).

According to Spanish sources, he also assembled a workforce of 150,000 men to undertake the monumental tasks of re-routing the Urubamba River to the south side of the valley, draining swamps, building agricultural terraces (andenes), irrigation canals, roads and bridges, ponds and parks, and constructing his palace at Quispiguanca, plus other secondary palaces.

He granted some land to his mother, other relatives, his wives, religious organizations, and a group of aclla, the sequestered women of the Incas who were often compared by the Spanish to Catholic nuns.

[4] The site of Huayna Capac's palace of Quispiguanca consisted in the early 21st century of a modern cemetery and fields of carrots and cilantro.

The inhabitants of the estate worked thereafter for Pizarro, contributing at first their labor as they had during the reign of Huayna Capac and later a fixed amount from their agricultural production.

[7] After Pizarro was killed in 1541, a Cañari Indian named Francisco Chilche claimed to be the overlord (cacique) of much of the land of the Quispiguanca estate.

)[8] Chilche continued to be important into the 1570s when he recruited 500 Indian soldiers to fight with the Spanish in their war against the last Inca, Tupac Amaru.
