In 1830, Dwarkanath Tagore, grandfather of Ravi Tagore and one of the members of the Jora Thakur family, came to this region. Later in 1891 Rabindranath Tagore first came to Patisar to look after the zamindari of Kaligram Pargana. In front of Patisar Ravi Tagore's kuthibari spread over an area of about 10 acres, one can see the lion door, wide courtyard, two-storied kuthibari and ruins of several buildings surrounding the kuthibari.
