Sachsenburg Castle rises near Frankenberg, Saxony, on a rock over the Zschopau river. The castle complex, which was built in the early 13th century at the latest, was converted into a castle in the 1480s. The complex is one of the few examples of a completely preserved late Gothic residential palace in Saxony.
The Lords of Sachsenburg were mentioned for the first time in 1197. It is uncertain whether a castle already existed at that time. Around 1210/30, however, the existence of the castle can be reliably proven on the basis of archaeological finds. The builders were evidently the Lords of Mildenstein.
Since 1610 the castle served as an administrative building for the Electoral Saxon Office of Sachsenburg with Frankenberg. During the Thirty Years War , the first and second outer bailey were destroyed and the castle looted.
From 1864 the castle was used as custody for young female prisoners and in 1867 a penal and correctional institution was established here. The property was only reserved for prisoners until 1926, and from 1914 onwards there were prisoners of war (Russians, including interned academics and students of the Freiberg Mining Academy , Englishmen, Serbs).
Along with Lichtenburg, Sachsenburg was among the first concentration camps to be built by the Nazis, and operated by the SS from 1933 to 1937. The camp was an abandoned four-story textile mill which was renovated in May 1933 to serve as a 'protective custody' facility for dissidents such as Jehovah's Witnesses, who opposed the Nazi regime.
Today the castle restoration is in progress.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
