Adhai-din-ka-Jhonpra (two-and-a-half-day shelter) is considered as the first important Islamic structure to be built in India. According to the legends, Arhai-din-ka-Jhonpra was a Sanskrit College initially and Mohammed Ghori converted the college into a mosque within two and a half days, hence the name. According to another legend, the structure is named after a festival, which carried on for two and a half days. The monument has seven arched walls with Islamic calligraphy, though most of it now remains in ruins.

The Taragarh Fort was built on a hilltop by Ajaipal Chauhan, the founder of the city in the 7th century and is about 3 km from the city of Ajmer. A steep climb up rewards the weary visitor with an amazing birds eye view of Ajmer. The first hill fort of India was built in 1100 by Ajayapal Chauhan. The fort gives excellent views of the town below and also known as the Star Fort. It has a thickness of four and a half meters and a winding uphill path leads to this rectangular fort. Most of the fort is now in ruins though at the time of its construction, it was supposed to be the invincible fort and so named as Ajai Meru (invincible fort).
