Ancient Inca Tunnels found under Cusco, Peru



Royal House of the Sun

The terraced pyramid at Sacsayhuaman is made of cyclopean polygonal masonry constructs over 1000 feet long, the largest block weighing 360 tons at a height of over 27 feet.

After his capture in Vilcabamba in 1572 the last Inca, Tupac Amaru, was incarcerated in Sacsayhuaman. The revolutionary leader Tupac Amaru II addressed his ultimatum for the Bishop of Cuzco to surrender the city from the hilltop sanctuary. Today the monument is used to present the pageant recreation of the religious portion of the prehistoric Festival of the Sun called Inti Raymi at the Winter Solstice June 24th.

Garcilaso de la Vega born April 12, 1539 in Cuzco, Peru, the illegitimate son of Spaniard Sebastian Garcilaso de la Vega, and an Incan princess, who wrote “Commentaries of the Incas”, reported that he personally knew that Sacsayhuaman had three towers.


“The fortress was a House of the Sun. Those of other nations were not able to enter the fortress, because it was a house of the sun. The largest and most magnificent work which the Inca ordered built to demonstrate their power and majesty was the fortress of Cuzco: Sacsayhuaman, the magnitude of which is incredible to those who have not seen it. Those who have seen and looked with attention believed that its greatness was made by way of enchantment and built by devils and not men, because the multitude of so many stones of such great size, such as those placed on the three terraces, caused vast speculataion. The massive stones cut from the quarries were moved and fitted so that the joint hardly shows. To think how they could fit stones so immense and so well, where one cannot even insert the blade of a knife inbetween them!

This find may form part of a series of galleries, chambers, fountains and ancient mausoleums located under the ancient Incan city of Cuzco. A tunnel measuring 2 km in length, linking the Koricancha Sun Temple with the fortress of Sacsayhuaman (located on the hillside above the city of Cuzco), was discovered by Spanish archaeologist Anselm Pi Rambla, in the ancient Inca capital. The tunnel may form part of a series of galleries, chambers, fountains and ancient mausoleums under the city of Cuzco, according the Wiracocha Project, initiated in 2000.


The group stated before the Peruvian Congress’s Cultural Commission that they had discovered the subterranean passageway, which may change perspectives on Peruvian history.

According to radar images, the tunnel links directly to the Temple of the Sun or Korikancha, with the Convent of Santa Catalina, or with the Cathedral or Temple of Inca Wiracocha, with the palace of Huascar, the Temple of Manco Capac or perhaps Colcampata and Huamanmarca.


All of these buildings are in a perfect astronomical alignment, confirming that ancient Peruvians also guided their constructions by the location of the Sun, the Moon and the constellations. Access to a tunnel at the Sacsayhuaman Fortress was already known, but it was condemned in 1923 to avoid the disappearances of curiosity seekers who entered it, since its trajectory was unknown.

The archaeologist explained that this would involve a “Pre-Inca citadel”, belonging to a culture that has yet to be considered. “We calculate that it would be some 100 meters under Cuzco…the great question is ascertaining what age it belonged to,” said the archaeologist. Excavation work aimed at confirming the location of the subterranean galleries confirm the stories of chroniclers like Garcilaso de la Vega and Cieza de León regarding an underground citadel in Cuzco.


This legacy of a civilization advanced beyond our own was capable of creating vast underground chambers, of which the surface markers point the way to the ingress. Engineering such vast chambers has been likened to the impact of contact with an advanced culture, and the discovery of the Fourth Root race, the so-called Atlantean civilization destroyed by the last earth upheavel.”
