Ahmednagar is a city in, and the headquarters of, the Ahmednagar district, Maharashtra, India. Ahmednagar has several dozen buildings and sites from the Nizam Shahi period. Ahmednagar Fort, once considered almost impregnable, was used by the British to house Jawaharlal Nehru and other Indian Nationalists before Indian independence. A few rooms there have been converted to a museum. During his confinement by the British at Ahmednagar Fort in 1944, Nehru wrote the book The Discovery of India.
