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:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
