One of the world's oldest mountain ranges, the Aravalli Range, cradles the only hill station of Rajasthan, Mount Abu, and its world-famous Dilwara Temples, a sacred pilgrimage for Jains. Eastern Rajasthan has two national tiger reserves, Ranthambore and Sariska, as well as Keoladeo National Park near Bharatpur, once famous for its bird life.
Rajasthan was formed on 30 March 1949, when all erstwhile princely states ruled by Rajputs, known as Rajputana, merged into the Dominion of India. The only difference between erstwhile Rajputana and Rajasthan is that certain portions of what had been British India, in the former province of Ajmer-Merwara, were included. Portions lying geographically outside of Rajputana such as the Sumel-Tappa area were given to Madhya Pradesh. Endowed with natural beauty and a great history, tourism is a flourishing industry in Rajasthan. The palaces of Jaipur, lakes of Udaipur, and desert forts of Jodhpur, Bikaner & Jaisalmer are rank among the most preferred destinations in India for many tourists both Indian and foreign. Tourism accounts for eight percent of the state's domestic product. Many old and neglected palaces and forts have been converted into heritage hotels.
Rajasthan is famous for the majestic forts, intricately carved temples and decorated havelis, which were built by Rajput kings in previous ages, they were the soul of pre-Muslim era Rajasthan. Jantar Mantar, Dilwara Temples, Chittorgarh Fort, Lake Palace, City Palaces, Jaisalmer Havelis are part of the true architectural heritage of India. Jaipur, the Pink City, is noted for the ancient houses made of a type of sand stone dominated by a pink hue. At Ajmer, the white marble Bara-dari on the Anasagar lake is exquisite.

Dilwara Temples of Mount Abu, Ranakpur Temple dedicated to Lord Adinath near Udaipur, Jain temples in the fort complexes of Chittor, Jaisalmer and Kumbhalgarh, Lodarva Jain temples, Bhandasar Temple of Bikaner are some of the best examples.
