Lindelbrunn Castle was founded in the mid-12th century, presumably as an imperial castle to defend the Trifels. Prior to that it may have been owned by the imperial church at Speyer. It is likely that the main construction phase of the castle with its palas and separate chapel dates to around 1190/1200. At that time, large halls and independent chapels were only built by relatively high-ranking lords; around 1200, not a single count had such a facilities. In 1274 the castle was transferred by King Rudolph of Habsburg to Counts Emich IV and Frederick III of Leiningen. In the course of time, Lindelbrunn became a joint-inheritance or Ganerbenburg. As a result of the enfeoffment of various parts of the castle, there were so many co-owners that disputes arose. In 1381, St. Nicholas' Chapel was first mentioned in a deed. In 1441 troopps of the Palatine prince-elector and the Bishop of Speyer, Reinhard von Helmstatt besieged the castle for seven weeks until a peaceful agreement ended the investment.
Shortly after Easter 1450, as a result of a feud and the seizure of Hans von Helmstadt, troops from the town of Landau and Bishopric of Speyer advanced on the castle. After four days of unsuccessful siege, Holzapfel was ransomed. In June that year, Count Emich VI of Leiningen-Hardenburg and his son, Frederick of Zweibrücken-Bitsch, besieged the castle, captured it and so ended the disputes.
During the German Peasants' War of 1525 the castle was razed by rebellious peasants of the Kleeburg Kolbenhaufen band. Since then it has remained unoccupied and fallen into ruins.
In 1963 the castle became the possession of the state of Rhineland-Palatinate. In 1979 to 1981 comprehensive remediation measures were carried out which saw the remains of the detached chapel being uncovered and partially restored.
The most important visible remains are the preserved parts of the palas (around 1190/1200) in the southwest of the castle. The outer wall on the valley side is made of rusticated ashlars and has three niches with adjacent windows and fireplace that has not quite been faithfully reconstructed. The interior probably contain a large hall.
From the forester's lodge, Forsthaus Lindelbrunn, it is a 15 to 20 minute walk to the ruins of Lindelbrunn Castle. In clear weather there is an extensive 360-degree panoramic view which also takes in the imperial castle of Trifels.
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.
