Surrounded by the soothing greenery of paddy fields, lies the 3rd Century BC Ashokan Rock Edict, a memory of the gruesome war that transformed Ashoka, the great Warrior into a Buddhist missionary. The Peace Pagoda built in collaboration with the Kalinga - Japanese Buddhist Sangha, on the opposite hill, is completely modern and is an excellent foil
