The glorious Liberation War of Bangladesh in 1971, led by "The Father of the Nation", Bangabandhu Sheikh Mujibur Rahman, was the final chapter in our struggle for independence. To encapsulate the military heritage of our Liberation War, an Army Museum' was established at the entrance of Mirpur Cantonment at Dhaka in March 1987, and was inaugurated on 26 November 1987. Between September 1997 and March 1999, the 'Army Museum' was shifted to its present location at Bijoy Sarani and was renamed as 'Bangladesh Military Museum' under the patronization of former Chief of Army Staff Lieutenant General Mohammad Mustafizur Rahman, Bir Bikram, ndc, psc, C. The museum was housed in a two-storied building. On 11 January 2010, Armed Forces Division formed a Board of Officers to renovate and modernize the museum with the Chief of General Staff of the Bangladesh Army as its chairman with members from three services. This Board of Officers proposed for a world-class museum and to name it 'Bangabandhu Military Museum'. The construction work of the present ‘Bangabandhu Military Museum’ had started from September 2017. ‘Toshakhana Jadu Ghor’ was first inaugurated on 15 November 2018 followed by the ‘Bangabandhu Military Museum’ that started its journey from 06 January 2022 after its inauguration by the Honorable Prime Minister Sheikh Hasina.
The three wings of the main building accommodates Bangladesh Army, Navy and Air Force separately. The basement floors are allotted to Bangladesh Navy for displaying additional artefacts. The ground floor is a combination of information, utility and it has entrances to the 'Toshakhana Jadughar' and the 'Victory Arena'. The first-floor displays exhibits of Bangladesh Army. The second floor is allotted to Bangladesh Air Force. A mezzanine floor houses the exhibits from Bangladesh's participation in the United Nations and contribution in Chattogram Hill Tracts. A separate four-storied administrative building has been built for administering, monitoring, supervising, maintenance and curatorial work of the museum.
