Regenstein Castle is a ruined castle that lies three kilometres north of Blankenburg in the German state of Saxony-Anhalt. It is a popular tourist destination where, each year, a knight's tournament and a garrison festival are held. Of this once relatively impregnable castle, which was built in the early and high Middle Ages on a 294 metre high sandstone rock towering over the surrounding area, only ruins are visible today. Several internal rooms, carved into the rock, have survived, as have the ruins of the keep. The castle is surrounded by remnants of a more recent fortress. Regenstein Castle is No. 80 in the system of checkpoints on the Harzer Wandernadel hiking trail network. Below the castle is the site of the old Regenstein Mill that used to supply it with water.
From 1671 the medieval castle was expanded into a fortress by the Prussians, who were the last users of its military function. The original castle occupies only a small part of the greater fortification. In 1677 the fort became a garrison. The length of its outer perimeter was extended in 1742 to 1,200 metres. Even under the French, to whom the fortress had to be handed over on 12 September 1757, it was extended structurally. The Prussians captured it five months later and rendered the position unusable. The powder magazine, which was located near the top was blown up. Of the fortress only the casemate, those facilities carved out of the rock and the gateway remain. A characteristic of the fortress is the large number of cavernous rooms in the natural rock. Even the stables were hewn out of the rock. After 1758, the pastures and forests of the Regenstein went to the Prussian Amt of Westerhausen. From 1815 to 1945, following the reign of Westphalia, Regenstein became the smallest Prussian exclave and belonged to the district of Halberstadt. Today it is part of the town of Blankenburg. Johann Wolfgang von Goethe visited the Regenstein on 11 September 1784 together with the artist, Georg Melchior Kraus, on his third trip to the Harz to conduct geological studies. The first restaurant was opened in 1812, thus beginning the rock's role as a tourist attraction.
The legend of the Regenstein
According to legend, once upon a time one of the most beautiful young women in the land was imprisoned in the dungeon of Regenstein Castle, because she had spurned the love of the Count of Regenstein. Using a diamond ring she scratched a hole in the rock, which became so large after a year that she was able to crawl through and escape. After her escape, she returned with her family to the castle, but the count had fled. A little later, she noticed thick smoke gushing from a crack in a rock wall. When she looked through it, she saw the count in purgatory. Then, out of pity, she threw him her ring to him in order to enable the spirit of the count to rest.
