Jodhpur  is the second-largest city in the Indian state of Rajasthan and officially the second metropolitan city of the state. It was formerly the seat of the princely state of Jodhpur State. Jodhpur was historically the capital of the Kingdom of Marwar, which is now part of Rajasthan. Jodhpur is a popular tourist destination, featuring many palaces, forts, and temples, set in the stark landscape of the Thar Desert. It is popularly known as the “Blue City” among people of Rajasthan and all over India.The old city circles the Mehrangarh Fort and is bounded by a wall with several gates. The city has expanded greatly outside the wall, though, over the past several decades. Jodhpur lies near the geographic centre of the Rajasthan state, which makes it a convenient base for travel in a region much frequented by tourists.
