Jaisalmer nicknamed “The Golden city”, is a city in the Indian state of Rajasthan, located 575 kilometres (357 mi) west of the state capital Jaipur. The town stands on a ridge of yellowish sandstone, and is crowned by the ancient Jaisalmer Fort. This fort contains a royal palace and several ornate Jain temples. Many of the houses and temples of both the fort, and of the town below, are built of finely sculptured sandstone. The town lies in the heart of the Thar Desert (the Great Indian Desert) and has a population, including the residents of the fort, of about 78,000. It is the administrative headquarters of Jaisalmer District. Jaisalmer was once the capital of Jaisalmer State.
Jaisalmer is named after Rawal Jaisal, a Bhati ruler[failed verification] who founded the city in 1156 AD. Jaisalmer means the Hill Fort of Jaisal. Jaisalmer is sometimes called the “Golden City of India” because the yellow sandstone used throughout the architecture of both the fort and the town below, imbues both with a certain golden-yellow light.
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 464 km (288 mi). It is located 790 kilometres away from the national capital Delhi.
