Mapped with Lasers: Checkout Derinkuyu 18-Level Underground CITY 280ft Deep 20,000 People Lived

Imagine a metropolis carved entirely out of volcanic rock, hiding 20,000 people beneath the surface of the Earth. Welcome to Derinkuyu. In this exclusive documentary, we take advanced LiDAR laser scanning technology 280 feet (85 meters) underground to map the 18 levels of the world's deepest excavated city in Cappadocia, Turkey. Join explorer and historian Viktor as we navigate the claustrophobic tunnels, reveal the massive millstone defense doors, and descend into the "Lost Sectors" never before seen by tourists. From the livestock stables on Level 1 to the submerged aquifer on Level 8, witness how an ancient civilization engineered a survival bunker that could withstand months of siege warfare. 🔦 IN THIS VIDEO: Laser Mapping: See the underground city revealed in 3D point-cloud accuracy. The Defense System: How massive 1,000lb rolling stones crushed invaders. Life Underground: Wineries, schools, and churches hidden in the dark. The Deepest Point: We reach the water table at the bottom of the abyss. 📍 LOCATION: Derinkuyu Underground City, Nevşehir Province, Turkey. 📅 ORIGIN: Phrygian/Byzantine Era (c. 8th Century BC - 12th Century AD). 🔔 SUBSCRIBE for more deep-earth archaeology and laser-mapped history! #Derinkuyu #UndergroundCity #AncientHistory #LiDAR #Archaeology #Cappadocia #Turkey #SecretTunnels #Documentary #4K #HistoryMystery
