final report

We want to express that, from the beginning, the Koricancha Project was a challenging endeavor for both the Peruvian government and us, due to the fact that the archaeological zone where the Incan temples (Koricancha) are located is the property of the ORDER OF PREACHERS OF SAINT DOMINIC OF GUZMAN. This property was granted to the Dominican Order in 1534 by Juan Pizarro, the half-brother of the conquistador Francisco Pizarro, shortly after the Spanish conquest of Cusco. The Dominicans built the Convent of Santo Domingo on its foundations, adapting the preexisting Incan structures.

Throughout the 20th century and the beginning of this century, no archaeological research had been conducted using modern technology in its subsurface. Only in the last 75 years have reconstruction works been carried out, led by architect Oscar Ladrón de Guevara after the 1950 earthquake, which destroyed part of the current church. Additionally, the PER-39 project (Plan Copesco, 1975/1985), supported by an international agreement between UNESCO and the Peruvian government, was implemented as part of a policy to conserve the historical-artistic heritage.

Paradoxically, the most important temple of the Inca Empire is, in reality, the least excavated and the most unknown. We wish to highlight that when we presented our project to the Peruvian government, whose goal was to investigate the existence of the tunnels mentioned by many chroniclers and researchers connecting Koricancha with the archaeological site of Saqsaywaman, the project would never have been possible without the intervention of the Prior of the Convent, Father Benigno Gamarra.

During our initial work, we used state-of-the-art remote sensing equipment with very satisfactory results. We discovered archaeological structures in many areas of the convent, including the Pinacoteca, the First Cloister, the Temple of the Stars, and, most importantly, in the church area where the following were found:

1) In the central nave, Incan walls beneath the Dominican coat of arms.

2) In the Gospel nave, a 17th-century colonial crypt near the transept and the Main Altar (Santa Rosa sector).

3) In the Epistle nave, the original foundations of the Hall of the Sun (the most important space in Koricancha) and its exact location, long sought after by researchers such as John Rowe. To our surprise, these foundations are not Incan but pre-Incan, made of green diorite, leading us to reassess the antiquity of Koricancha.

4) In the bell tower, highly disturbed colonial burials were found (a mass grave). In the southern part, a double surface wall built with Killke stone was identified, where a series of completely aligned skulls (ritual type) were attached to the wall.

Despite all these significant discoveries, the georadar did not locate the crypt containing the entrance to the tunnel (Chinkana) through which Anselm Pi Rambla, Frances Serrat, and the Prior of the Convent entered in 1982. The hasty conclusion reached by the Dominicans and some authorities was that the crypt and tunnel (Chinkana) were not located in the church sector, as the radar did not detect them.

Given this situation, it was decided to suspend the work temporarily with the permission of the INC (National Institute of Culture) to clarify the findings. Some critical excavated areas were left open and consolidated because we suspected they had been altered by the Dominicans, and it was unclear why the radar failed to detect the crypt and tunnel. We requested authorization from Prior Héctor Herrera to open an adjacent area of the Hall of the Sun, in the Epistle sector, where the radar indicated significant anomalies. However, at that point, the situation changed drastically. The Dominicans prohibited further work, disagreed with our proposals, and, in coordination with the Cusco National Institute of Culture, agreed to permanently close the project.

On August 19, 2003, an agreement was signed at the Cusco National Institute of Culture, obliging Pi Rambla to finance the closure of the work and permanently leave Koricancha. A month later, the closure of the work and the definitive termination of the project were handed over to the Peruvian government. However, shortly after, the Peruvian press (El Comercio, 08/23/2003) reported that the company had endangered the church's structures, labeled them treasure hunters, and described the entire project as a fraud.

We want to emphasize, despite denials by some historians and archaeologists, that the Dominicans have long known about the existence of the tunnel (Chinkana) beneath Koricancha. Since the time of Francisco Pizarro, they were the first to discover it. After the 1650 earthquake, the church area built over the Incan temples was completely remodeled. Several crypts were built beneath the Main Altar, and the transept, floor, and some zones affected by the earthquake were modified.

Today, we know that from the 18th century until 1982, the fifth crypt remained completely sealed, with access restricted. Between 1986 and 1988, for unknown reasons (possibly related to the 1986 earthquake), the Dominicans decided to seal, block, and permanently hide the area. They replaced the wooden floor in the Epistle sector, where the crypt entrance was located, with tile flooring. This closure was kept strictly secret, and only a few Priors of the Convent were aware of it. Father Gamarra, as Prior and architect of the 2000 agreement signed with the government and our society, knew about the Chinkana from information passed down by his predecessors but did not know its exact location within the church or the extent of its concealment. In fact, we have evidence that in 1940, two priests entered the Chinkana and reached the famous labyrinths of Saqsaywaman mentioned by Inca Garcilaso de la Vega.


Before concluding this report, we wish to disclose for the first time that, despite the forced closure of the project, we continued analyzing all excavation reports and thoroughly reviewed the georadar data. Unsurprisingly, thanks to advanced technology and meticulous attention to detail in our research, we were able to accurately locate the crypt (fifth crypt) within the church, in the sector where Anselm Pi Rambla, Francesc Serrat, and the Prior entered in 1982.

Therefore, we are pleased to inform the international community that THE FIFTH CRYPT AND THE CHINKANA EXIST AND ARE REAL.
