During the 47 years of Soviet occupation in Estonia approximately 122,000 people fell victims to different repressions from the security organs and more than 30,000 of them lost their life. The South Centre of Soviet security service NKVD and later KGB was located in Tartu, in the so-called gray house.
The dungeon was located in the basement and cells have been restored to the original appearance as part of the museum's permanent exhibition. The KGB Museum reflects the Soviet occupation of Estonia and the history of Estonian Resistance Movement. In the display you can find plans drawn by the Soviet authorities for conducting deportation operations, leaflets distributed by the school children's underground organizations, objects from the GULAG prison camps, as well as a great number of other photos and documents illustrating Estonian near history.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
