Sabarna Sangrahashala is a museum about the Sabarna Roy Choudhury family, who had transferred by lease their rights over three villages to the East India Company. The highlight of the museum is the historic judgement of the Kolkata High Court regarding the Kolkata Birthday Case and the expert committee report on the matter, which states that Job Charnock was not the founder of Calcutta (Kolkata), nor is 24 August is the city's birthday: Kolkata was an important trade and religious centre even before the arrival of Charnock. The establishment of this museum was as a family effort to restore and correct this distorted notion of history that is widely prevalent. This is the only museum in the country that is run by a family and possesses rare documents and articles, including Kabilatipatras dating back to the 18th and 19th centuries: an important holding being one which has signature of Kavi Rama Prasad Sen dated 1794. Other articles include a huge earthen rice pot dating 1840 with a capacity for 240 kg of grain, a metal hookah dated 1878, a metal candle stand dated 1795, and grinding wheels dated 1845. The philatelic and numismatic divisions possess rare stamps and coins. The museum organises an International History & Heritage Exhibition every year in the month of February based on different themes showcasing exclusive important resources of history which also has seminars, cultural events and open quiz as a part of the event.
