The museum building, together with its garden, is built on an area of one thousand 290 square meters. Built between 1910 and 1915 by Major Baha Bey, the head of the Military Branch of the period, as a three-storey house with a ground floor, the house was later purchased by Hasan Cavit Bey, a close friend of Atatürk and a member of parliament. On June 17, 1922, Mustafa Kemal Atatürk met with his mother and stayed for three days in this house, which was severely damaged in the earthquake in 1967. In 1983, the house, which was registered as an example of civil architecture, was expropriated by our Ministry and rebuilt in reinforced concrete with its exterior appearance in accordance with its original appearance and completely modified inside.
