The oldest part of Junagadh, and the center of any visit to the city, is the upper citadel, known as Uparkot. Over 2300 years old, with walls up to 20 m high in some places, Uparkot is what allowed Junagadh to withstand a 12-year siege at one point. It is believed that these caves belong to 1st-4th Century AD and are gilded with beautiful pillars and entrances, water cisterns, horseshoe shaped chatiya windows, an assembly hall and cell for meditation. There is also a 300 ft.-deep moat inside the walls, that reportedly used to be inhabited by crocodiles, so that if any attacker managed to surmount the high fortifications, they would then either be exposed on the upper battlements or fall into the crocodile-infested trench.
