Magazine, the city's Museum, was once the residence of Prince Salim, son of Emperor Akbar, and presently houses a collection of the Mughal and Rajput armour and sculpture. This residence of Salim is significant from a historical point of view, because Salim as Emperor Jahangir read out the firman for trade to India to the British East India company from here, thus starting the chain of events that lead to India's colonisation by the British.

The summit of Taragarh hill, overhanging Ajmer, is crowned by a fort, the lofty thick battlements of which run along its brow and enclose the table-land. The walls are 3 km in circumference, and the fort can only be approached by steep and very roughly paved planes, commanded by the fort and the outworks, and by the hill to the west. On coming into the hands of the British Raj, the fort was dismantled by order of Lord William Bentinck, and was converted into a sanatorium for the troops stationed at the British cantonment town of Nasirabad.

Mayo College was established in 1875 by Lord Mayo, Viceroy of India. The architecture of the school buildings evoke the grandeur of erstwhile princely Rajasthan. The main building of the school, in white marble, is a classic example of Indo-Saracenic architecture, and the design now lies in the archives of the British Museum in London.

The Cathedral of the Immaculate Conception is the seat of the Roman Catholic Diocese of Ajmer.
