Taragarhor the 'Star Fort' is situated three kilometers and a steep 1 and a half hour climb beyond the Adhai-Din-Ka-Jhonpra Mosque. As it is situated on a height, it commands a spectacular view over the city. It was built by Ajaipal Chauhan, the town's founder. The fort was the site of much military activities during Mughal times and was later used as a sanatorium by the British.
Situated at the foot of a hill and in the old part of town, this is one of the most important places in india for muslim pilgrims. The Dargah is the tomb of a Suffi saint, Khwaja Muin-ud-din Chishti, who came to Ajmer from Persia in 1192 and died here in 1236. Construction of this shrine was completed by Humayun and the gate was added by the Nizam of Hyderabad. Akhbar used to make the pilgrimage to the Dargah from Agra once a year.
Adhai Din Ka Jhonpra
Beyond the Dargah, on the outskirts of town, are the ruins of Adhai-Din-Ka-Jhonpra mosque. According to legend its construction, in 1153, took just 2 and a 1/2 days. (Adhai-Din-Ka-Jhonpra means '2 and a 1/2 day building'). Others believe it was named after a festival that lasted for 2 and a 1/2 days . It was originally built as a Sanskrit college , but in 1198 Mohammed of Ghori took Ajmer and converted the building into a mosque by adding a seven-arched wall covered with Islamic calligraphy in front of the pillared hall.
