Rauenstein Castle guarded the crossing over the River Flöha along the road from Freiberg to Annaberg. The castle is first mentioned in 1323, although from archaeological investigations it is postulated that it had been built by around 1200. The first lords of Rauenstein were the Schellenbergers.
After several changes of ruler, the castle went into the possession of the Electorate of Saxony in 1567. The Amt of Rauenstein was given to Wolkenstein in 1596. Around 1630 large structural changes were made. The road tunnel also dates to this time.
From 1651 to 1743 the castle was rented to the von Römer family, who had become very wealthy as a result of silver mining in the Schneeberg area. Its owner, Christian August Hähnel, who had bought Rauenstein in 1816, his nephew, Wolfgang, Freiherr von Herder (owner from 1843 to 1853) and another family member, Wilhelm Freiherr von Herder, were members of the Saxon Landtag. The next owner, Gottfried Freiherr von Herder, was a German Conservative Reichstag MP from 1893 to 1898.
After its confiscation as part of the land reform in the Soviet Zone of Occupation in 1945, the castle was used as a children's convalescent home. It has been owned by a private family since 1998 and may now only be viewed from the outside.
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.
