The Udayagiri and Khandagiri hills are located near Bhubaneswar, Odisha, and are known for their rock-cut caves. The caves are partly natural and partly artificial, and were built between the 1st and 2nd centuries BC. The caves are considered to be a relic of a forgotten chapter of history, and are a testimony to India's rich past. They are also said to bear messages of love, compassion, and religious tolerance.
