Mani Bhavan is a simple old-style, two storied building in Mumbai. Whenever Mahatma Gandhi was in Mumbai between 1917 to 1934, he stayed here. It is now converted into a museum and research centre. It belonged to Shri Revashankar Jagjeevan Jhaveri, who was Gandhi's friend and a host during that period.
It was from Mani Bhavan that Mahatma Gandhi initiated the Non-Cooperation, Satyagraha, Swadeshi, Khadi and Khilafat movements. Gandhi's association with the charkha (Spinning Wheel) began in 1917, while he was staying at Mani Bhavan.
The room on the second floor which used to be the living room and working place of Gandhiji has been preserved as far as possible in its original setting.
Inside the house is a library of Gandhi-related works (about 50,000 books and periodicals), a photo exhibition of the Mahatma's life, and well preserved memorabilia, including an old charkha or spinning wheel that Gandhiji used to use.
On the terrace, a bronze plaque marks the site of the tent in which Gandhi was arrested in January 1932. He also used to sleep and say his prayers on this terrace.
