The 600-Year-Old Underground Water Tunnel Beneath Bidar | India's Hidden Engineering Marvel

The 600-Year-Old Underground Water Tunnel Beneath Bidar | Bharat Unfolded 🎬 New Documentary Did you know that beneath the streets of Bidar lies a 600-year-old underground tunnel system that still carries water today? In this Bharat Unfolded documentary, we uncover the remarkable story of Bidar Karez—an ancient underground water supply system built during the Bahmani Sultanate that transported groundwater across the city without electricity, pumps, or modern machinery. For more than six centuries, this extraordinary engineering system has silently continued to function beneath one of India's greatest medieval forts. The story unfolds: • What exactly is the Bidar Karez system? • Why was an underground water network built beneath Bidar? • How Persian engineering transformed water supply in medieval India • The ingenious gravity-fed tunnel system and vertical access shafts • How workers excavated kilometres of tunnels without modern equipment • Why the Karez was forgotten for centuries • How historians and conservation teams rediscovered the system • Why water still flows through parts of the Bidar Karez today • Why this forgotten engineering marvel deserves to be remembered alongside the world's greatest hydraulic systems 📺 Enjoyed this documentary?
