Taragarh Fort, the fort guarding Ajmer

Taragarh Fort, the fort guarding Ajmer, was the seat of the Chauhan rulers. It is reputed to be one of the oldest hill forts in India and the world. It was built by King Ajaypal Chauhan on the summit of Taragarh Hill and overlooks Ajmer. The battlements run along the top of the hill. The walls are two miles (3 km) in circumference and the fort can only be approached by way of a very steep slope. When it fell to the British Raj, the fort was dismantled on the orders of Lord William Bentinck and was converted into a sanatorium for the British troops stationed at the garrison town of Nasirabad.
