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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
