Scientists Scanned Beneath Cusco: What They Found Should NOT Exist!
Swiss ground-penetrating radar just confirmed what Spanish chroniclers described 400 years ago — a 1,750-meter tunnel system stretching from Sacsayhuamán to the Temple of the Sun beneath the streets of Cusco, Peru.
On January 6, 2025, Peruvian archaeologists Jorge Calero Flores and Mildred Fernández Palomino announced definitive evidence of the legendary Chinkana labyrinth. The total network may span 8 kilometers. Explorers vanished inside these tunnels in 1624. Authorities dynamited the entrance in 1927. For centuries, the official position was: these tunnels don't exist.
Now radar says otherwise.
In this documentary, we trace the complete story — from Inca Garcilaso de la Vega's 1609 account and the anonymous 1594 Jesuit chronicle, through the disappearances and sealed entrances, to the Swiss Proceq GS8000 Pro radar that mapped the underground corridors in real-time 3D. We examine the megalithic engineering of Sacsayhuamán above, where 200-tonne stones are fitted without mortar, and ask what the pending radiocarbon dates from the University of Warsaw excavation might reveal about the true age of the site.

Scientists Found 12 Hidden Structures at Machu Picchu
In 2021, Polish archaeologists used LiDAR drones to scan the jungle around Machu Picchu. What they found should have changed everything we know about the Inca: 12 previously unknown structures, hidden beneath the canopy for 500 years. Some of them just 60 feet from areas tourists walk through every day. The team published their findings in a peer-reviewed journal. They planned excavations for 2022. Then the excavations were cancelled. And never rescheduled. Four years later, those 12 structures are still buried. No excavation. No explanation. Meanwhile, in January 2025, Peru confirmed the existence of a legendary 1,750-meter tunnel system beneath Cusco using the exact same radar technology. They're excavating it this spring. Same technology. Same country. Different treatment. Why is Peru digging up one discovery but refusing to touch the other? In this video, we investigate:
