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.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
