Known as the gateway to the Thar Desert, Jodhpur is the second-largest city in the state of Rajasthan, India. It is a popular tourist destination featuring a variety of ornate palaces, age-old forts, and sacred temples. Dubbed ‘The Blue City’, the old city contains houses in a beautiful shade of indigo. While Jodhpur is largely a sprawling modern metropolis, enclosed within its old city walls is a labyrinth of winding, narrow medieval streets, and bazaars. The massive 15th-century Mehrangarh Fort, which towers over the city from its sandstone plinth, is one of the largest in the country. Other must-see attractions include the Umaid Bhawan Palace, one of the world's largest private residences; and the Jaswant Thada, an intricately carved white marble mausoleum.
