It’s a pleasure to introduce the KORICANCHA & SAQSAYWAMAN PROJECT, an archaeological scientific project of great interest to the international community. This project refers to the investigations and excavations that we carried in the two majors solar temples of the Inca Empire, such as: the KORICANCHA (actually the Convent of Santo Domingo) and SAQSAYWAMAN in Cusco (Peru).

The project is based on the remarkable information gathered by early chroniclers, colonial historians, researchers and archaeologists of the XIX and XX centuries indicating that the two Solar Temples were communicated through a tunnel (CHINKANA in Quechua language) of 1200 meters, which starts from the Koricancha crossing the entire city of Cusco, and linking the most important palaces of the Inca sovereigns as an umbilical cord, ending its route in the subway labyrinths of the citadel of Saqsaywaman mentioned by Garcilaso de la Vega in his Comentarios Reales. At these labyrinths, the Incas hid part of the sacred pieces and other precious metals which were preserved in the Koricancha and constituted the fundamental aspect of the religion of the Tawantinsuyo.

Until now, these structures had not been documented or scientifically investigated and no rigorous excavations had been carried out in the KORICANCHA because of the Order of Santo Domingo (owner of the Koricancha Complex) had not allowed extensive excavations within its property, which occupies an archaeological area of the utmost importance in terms of monuments of Inca and pre-Inca origin.

The AGREEMENT that we signed with the NATIONAL INSTITUTE OF CULTURE OF PERU and with the ORDER OF THE DOMINICANS OF CUSCO, allowed us to carry out exhaustive investigations in the subsoil of KORICANCHA through the application of high technology, remote sensing systems Georadar (Ground Penetrating Radar) and systematic excavations under the current floor of the church that corresponded to the main enclosure of the ancient TEMPLE OF THE SUN OF THE INCAS.

We also signed an agreement with the NATIONAL INSTITUTE OF CULTURE OF CUSCO that facilitated the excavations in the area of SAQSAYWAMAN, in the CHINKANA GRANDE area, where supposedly the entrances to the complex system of Inca tunnels existed.

The results obtained from all these works allowed us to locate the existence of these subway structures and to unravel the MYSTERY OF THE TUNNELS.
