The Kaunas Fortress was a military project implemented by Russian government. In 1879 Russian Emperor Alexander II accepted a suggestion to build military fortress in Kaunas in order to defense the western border of Russian Empire from German invasion. In the general plan of fortifications there were many objects intended to be built like a surround of 7 fortresses and 9 interjacent artillery batteries, defensive centers, military train station, workshops, stores and many more.
Fortresses were built at the approaches to Kaunas city in distances of 2-2,5 km. The line of set fortresses formed almost a regular oval by 4000 workers annually. Total of 250 wooden and 200 stone buildings serving for military purposes were erected in the territory of Kaunas fortification. However, as building works were slower than modernization of technique, the Kaunas Fortress had to be modernized several times too. In 1912 the Kaunas Fortress had to be double widened, but a broke out of the First World War stopped the works. In the World War I (1915) an army of 90 000 soldiers was garrisoned in the Kaunas Fortress to sustain a siege of German military forces. After 11 days of siege, Germans finally smashed into the Kaunas Fortress. During the assault 4000 defenders and more than 4000 German soldiers died. 20 000 defenders were taken captive. More than 1300 various cannons, guns and military stores were taken by Germans.
After the First World War, some of fortifications were dismantled and the rest served for the troop and Kaunas city. During the Second World War Kaunas Fortress was not used for defensive purposes any more. The Sixth, the Seventh and the Ninth forts were used as concentration camps by German army. About 50,000 people were executed there, including more than 30,000 victims of the Holocaust.
In the postwar period Soviet occupants established military bases in most of these forts. The old buildings of fortification were not preserved as they were demolished and rebuilt. After Soviet military forces were pulled out, military bases located in forts were liquidated. As Kaunas city expanded, some of these forts got into territory of Kaunas city and were surrounded by living houses and city streets, interblending into an environment of Kaunas city.

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.
