[1][2][3][4] Pagari 1, when built in 1912, was intended as a residential building.
However, in March 1918, the building housed the Estonian Provisional Government.
Furthermore, the Estonian War of Independence (1918–1920) was coordinated from Pagari 1.
[2][4][3] For almost half a century, Pagari 1 housed the headquarters of the ESSR's People's Commissariat of Internal Affairs, or the NKVD, later known as the KGB.
The museum has one permanent exhibition, ‘History of the KGB House’, and regularly hosts other temporary exhibitions.
