Chitradurga: The ancient fort with legends and water harvesting
Steeped in legends and folklore from the Mahabharata era, the Chitradurga Fort in Karnataka is also an engineering marvel. While its seven concentric fortification walls provided multiple layers of defence, its advanced rainwater harvesting system ensured the fort atop rocky hills never faced a water shortage. The 11th-century water reservoirs inside Chitradurga store water even today.
