Passage: Mughal architecture greatly influenced the architectural style of several buildings of the fort. Constructed of red sandstone and marble, the attractive, opulent palace is laid out on four levels, each with a courtyard. It consists of the Diwan-e-Aam, or "Hall of Public Audience", the Diwan-e-Khas, or "Hall of Private Audience", the Sheesh Mahal (mirror palace), or Jai Mandir, and the Sukh Niwas where a cool climate is artificially created by winds that blow over a water cascade within the palace. Hence, the Amer Fort is also popularly known as the Amer Palace. The palace was the residence of the Rajput Maharajas and their families. At the entrance to the palace near the fort's Ganesh Gate, there is a temple dedicated to Shila Devi, a goddess of the Chaitanya cult, which was given to Raja Man Singh when he defeated the Raja of Jessore, Bengal in 1604. (Jessore is now in Bangladesh).This palace, along with Jaigarh Fort, is located immediately above on the Cheel ka Teela (Hill of Eagles) of the same Aravalli range of hills. The palace and Jaigarh Fort are considered one complex, as the two are connected by a subterranean passage. This passage was meant as an escape route in times of war to enable the royal family members and others in the Amer Fort to shift to the more redoubtable Jaigarh Fort. Annual tourist visitation to the Amer Palace was reported by the Superintendent of the Department of Archaeology and Museums as 5000 visitors a day, with 1.4 million visitors during 2007. At the 37th session of the World Heritage Committee held in Phnom Penh, Cambodia, in 2013, Amer Fort, along with five other forts of Rajasthan, was declared a UNESCO World Heritage Site as part of the group Hill Forts of Rajasthan.
