Lohagarh Fort

Lohagarh Fort is a fort located at Bharatpur in Rajasthan, India. It stands as a testament to the strength and ingenuity of the Jat rulers of Bharatpur, particularly Maharaja Suraj Mal, who commissioned its construction in 1732. The British army attempted to conquer this fort 13 times but they could not penetrate the fort even once. The inaccessible Lohagarh fort could withstand repeated attacks of British forces led by Lord Lake during The Siege of Bharatpur in 1805 when they laid siege for over six weeks, yet failed in all four attempts to storm the fortress.

Between December 1825 and January 1826, British troops under Lord Combermere initially surrounded the state's capital until on 18 January 1826 its fortress was stormed and captured. After this siege, Bharatpur became a princely state under British Raj control.
