The Ranthambore Fort in Rajasthan lies within the Ranthambore National Park. The park once used to be the hunting grounds of the Maharajahs of Jaipur until the time of India's Independence. It is a formidable fort having been a focal point of the historical developments of Rajasthan. The fort was held by the Chahamanas (Chauhans) until the 13th century, when the Delhi Sultanate captured it. In 2013, at the 37th session of the World Heritage Committee, Ranthambore Fort, along with 5 other forts of Rajasthan, was declared a UNESCO World Heritage Site under the group 'Hill Forts of Rajasthan'.
