Rheingrafenstein Castle lies on a 136-metre-high porphyry rock formation on the river Nahe, opposite Bad Münster am Stein-Ebernburg. The rock castle was probably built in the 11th or 12th century by the Counts of Nahegau of the Emichones family. It was definitely the ancestral castle of the Lords of Stein, the later Wild- and Rhinegraves, and it remained in their possession until the French Revolution. The Lords of Stein were first mentioned in the 12th century. Their relationship to the Counts of Nahegau is unclear. Rheingrafenstein Castle itself is first unambiguously mentioned in the 13th century. The Lords of Stein acquired the Rheingau in the second half of the 12th century through marriage. In 1196, Lord Wolfram of Stein began styling himself Rhinegrave. This title was later attached to his castle.
During the Thirty Years' War, the castle was captured by French and Spanish troops. In 1688, it was destroyed by general Mélac. In 1721, a salt works was built on top of the castle's ruins. The castle's last owner, the Prince of Grumbach, moved his residence to nearby Gaugrehweiler.
Parts of the enceinte, a vaulted cellar, a few steps of the former tower house, and the foundations of the former tower staircase are still standing. Another staircase leads through the rocks to a viewing platform.
On the southern slope of the rock, the ruins of the bailey Affenstein can be seen.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
