Museum of the Occupation of Latvia 1940-1991 (Latvijas okupācijas muzejs) is an historic educational institution. It was established in 1993 to exhibit artifacts, archive documents, and educate the public about the 51-year period in the 20th century when Latvia was successively occupied by the USSR in 1940, then by Nazi Germany in 1941, and then again by the USSR in 1944.
The museum's stated mission is to show what happened in Latvia, its land and people under two occupying totalitarian regimes from 1940 to 1991, remind the world of the crimes committed by foreign powers against the state and people of Latvia and remember the victims of the occupation: those who perished, were persecuted, forcefully deported or fled the terror of the occupation regimes.
The building of the museum was built already in 1971 to celebrate Lenin's 100th birthday and up until 1991 it served as the Museum of Red Latvian Riflemen.

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.
