he Dargah Sharif of Khwaja Mu'inuddin Chishti is situated at the foot of the Taraga?h hill, and consists of several white marble buildings arranged around two courtyards, including a massive gate donated by the Nizam of Hyderabad and the Akbari Mosque, built by the Mughal emperor Shah Jahan. It contains the domed tomb of the saint. Akbar and his queen used to come here by foot on pilgrimage from Agra every year in observance of a vow when he prayed for a son. The large pillars called "Kose ('Mile') Minar", erected at intervals of two miles (3 km) along the entire way between Agra and Ajmer mark the places where the royal pilgrims halted every day. It has been estimated that around 125,000 pilgrims visit the site every day.
Taraga?h 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 Taraga?h 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.
