Colditz Castle is located on a hill spur over the river Zwickauer Mulde, a tributary of the River Elbe. In 1046, Henry III of the Holy Roman Empire gave the burghers of Colditz permission to build the first documented settlement at the site. During 1158, Emperor Frederick Barbarossa made Thimo I the Lord of Colditz, and major building works began. By 1200, the town around the market was established. During the Middle Ages, the castle was used as a lookout post for the German Emperors and was the hub of the Reich territories of the Pleissenland.
As a result of family dynastic politics, the town of Colditz was incorporated into the Margraviate of Meissen. During 1430, the Hussites attacked Colditz and set town and castle on fire. Around 1464, renovation and new building work on the castle were done by order of Prince Ernest, who died in Castle Colditz in 1486. During the reigns of Electors Frederick III the Wise and John the Gentle, Colditz was a royal residence of the electors of Saxony.
During 1504, the servant Clemens the baker accidentally set Colditz afire, and the town hall, church, castle and a large part of the town was burned. During 1506, reconstruction began and new buildings were erected around the rear castle courtyard. During 1523, the castle park was converted into one of the largest zoos in Europe. During 1524, rebuilding of the upper floors of the castle began. There is nothing more to be seen of the original castle, where the present rear of the castle is located.
The structure of the castle was changed during the long reign of the Elector Augustus of Saxony (1553–86), and the complex was reconstructed into a Renaissance style castle from 1577 to 1591, including the portions that were still in the Gothic architectural style.
In 1694, its then-current owner, King Augustus the Strong of Poland, began to expand it, resulting in a second courtyard and a total of 700 rooms.
During the 19th century, the church space was rebuilt in the neo-classic architectural style, but its condition was allowed to deteriorate. The castle was used by Frederick Augustus III, Elector of Saxony as a workhouse to feed the poor, the ill, and persons who had been arrested. It served this purpose from 1803 to 1829, when its workhouse function was assumed by an institution in Zwickau. During 1829, the castle became a mental hospital for the 'incurably insane' from Waldheim. During 1864, a new hospital building was erected in the Gothic Revival style, on the ground where the stables and working quarters had been previously located. It remained a mental institution until 1924.
When the Nazis gained power during 1933, they converted the castle into a political prison for communists, homosexuals, Jews and other people they considered undesirable. Starting 1939, allied prisoners were housed there. After the outbreak of World War II, the castle was converted into a high security prisoner-of-war camp for officers who had become security or escape risks or who were regarded as particularly dangerous. Since the castle is situated on a rocky outcrop above the River Mulde, the Germans believed it to be an ideal site for a high security prison.
References:Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
