In Bharatpur's Old City, this solid-looking fort, surrounded by a deep and wide moat, is also known figuratively as the Iron Fort, though it's built of mud. It has a colossal metal door. The structure might seem fragile, but it was tested and found invincible by a British siege in 1805: armed with 65 pieces of field artillery, 1,800 European soldiers and 6,000 Indian sepoys did manage to win the battle, but they failed to break down the impregnable fort. There are palaces
inside the fort and a musuem that showcases wall paintings and pieces of sculpture and toys excavated nearby and dating from the 2nd century.
