The former office of the KGB Deputy Chief of Internal Prison on the museum’s first floor includes an exhibition of documents, photographs, maps and other items depicting the Sovietisation of the region in 1940-1941. The exhibition dedicated to the guerrilla war of 1944-1953 introduces the territorial structure and military organization of the guerrilla units, the aspirations of freedom fighters, their daily activities, and their everyday life. The NKVD-NKGB fight against armed resistance is revealed in the Unfair Fight exhibition.
The museum’s second floor has an exhibition dedicated to the imprisonment of Lithuanians in gulags from 1944 to 1956, deportations from 1944 to 1953, and KGB activities from 1954 to 1991.
The Museum of Occupations and Freedom Fights was established in 1992. It is the only such museum in the Baltic States, housed in the same building where the repressive Soviet authorities NKVD and NKGB-MGB-KGB worked from the second half of 1940 until August 1991. The building’s basement contains an internal prison-interrogation isolation cell where residents of Lithuania who seemed suspicious to the occupation authorities were imprisoned from the autumn of 1940 until 1987. Visitors can get acquainted with the exhibition, which was set up in the former death penalty enforcement room.
