'Jewel House') is a museum and historical building dedicated to Gandhi, situated at Laburnum Road in the Gamdevi precinct of Mumbai.
The mansion belonged to Revashankar Jagjeevan Jhaveri, Gandhi's friend and host in Mumbai during this period.
It was from Mani Bhavan that Gandhi initiated the Non-Cooperation, Satyagraha, Swadeshi, Khadi and Khilafat Movements.
Mani Bhavan is also closely associated with Gandhi's involvement in the Home Rule Movement, as well as his decision to abstain from drinking cow's milk in order to protest the cruel and inhuman practice of phookan meted out to milch cattle common during that period.
A staircase dotted with Gandhi's pictures depicting his life leads visitors to the first floor which has a photo gallery with photographs from his childhood till his assassination, along with press clippings.
