Have you ever wondered what lies beneath the historic streets of Cusco, the heart of the Inca Empire? Recent archaeological discoveries have unveiled a fascinating network of underground tunnels that connect some of the most iconic ancient sites in the region. These findings not only shed light on the ingenuity of Inca engineering but also invite you to explore the depth of Peru’s cultural heritage.
A Hidden Labyrinth: The Discovery of Chincanas
On January 6, archaeologists announced the verification of an underground network of Inca tunnels, known as chincanas (Quechua for "labyrinth"). This intricate system links major archaeological sites, including the spiritual center of Coricancha, the imposing fortress of Sacsayhuamán, and the significant areas of Muyumarca and Callispuquio.
Spanning 1,750 meters in length and reaching depths of up to 2.5 meters, these tunnels reflect the advanced urban planning and engineering of the Tahuantinsuyo—the vast Inca Empire. Researchers have even discovered additional branches extending to other archaeological sectors, emphasizing the strategic and cultural significance of these subterranean corridors.
What Are Chincanas?
Historically, chincanas were more than just passageways. These tunnels served as vital routes for communication, ritualistic purposes, and strategic planning. The advanced construction techniques, such as trapezoidal stone walls and expertly placed beams, highlight the Inca’s unparalleled craftsmanship.
Chroniclers such as Garcilaso de la Vega described these underground streets as "avenues connecting temples and fortresses," bridging spiritual, administrative, and urban functions. This discovery reinforces how deeply the Andean worldview was interwoven with the infrastructure of the Inca civilization.
Walking Through History: From Coricancha to Sacsayhuamán
The newly discovered tunnel system connects two of Cusco’s most celebrated landmarks. Coricancha, the spiritual heart of the Inca Empire, and Sacsayhuamán, a fortress known for its colossal stone walls, are now revealed to have been linked beneath the city. Additional branches of the tunnels extend to Muyumarca and Callispuquio, further demonstrating the Inca’s meticulous territorial planning.
This groundbreaking revelation offers new insights into the Tahuantinsuyo’s organization, where every structure and pathway was part of a carefully designed urban plan. The tunnels exemplify the Incas’ harmony with their environment and their ability to integrate subterranean constructions with surface-level developments seamlessly.
How Were the Tunnels Discovered?
The discovery of the chincanas is the result of decades of interdisciplinary research. Archaeologists Jorge Calero and Mildred Fernández, supported by a multidisciplinary team, utilized historical records and cutting-edge technology.
Sound tests revealed echoes indicative of hollow spaces, while georadar confirmed the existence of voids enclosed by trapezoidal walls—a hallmark of Inca construction. Their meticulous approach culminated in the identification of these tunnels, which are set to be further excavated in 2025.
