The driest place in India is Jaisalmer. Jaisalmer is a former medieval trading center and a princely state in the western Indian state of Rajasthan, in the heart of the Thar Desert. Known as the "Golden City," it's distinguished by its yellow sandstone architecture. Dominating the skyline is Jaisalmer Fort, a sprawling hilltop citadel buttressed by 99 bastions. Behind its massive walls stand the ornate Maharaja's Palace and intricately carved Jain temples. It is the largest district of Rajasthan and 3rd largest district by territorial region in the country, hugged on the west & south-west by the Pakistani border. The length of the international border attached to Jaisalmer District is 471 km (293 mi). It is located 790 kilometers away from the national capital Delhi.
