Saalkirche, today a Protestant church, was constructed on a cross‐shaped floor in the 10th century as a further sacral building in the Ingelheim Pfalz. Thus the imperial palace reached its closed U‐shaped form, which had already been foreseen in the Carolingian building concept. In the following centuries the church was constantly remodelled, mainly in the 12th century. Integrated into a monastery in 1345, the church overcame the resettlement of the former Pfalz area, the so‐called ‘Ingelheimer Saal’ to which the name of the church refers. Given up in course of Reformation the building became dilapidated. In 1965 its reconstruction was completed. A small exhibition on the Ottonian period of the Pfalz was opened inside in 2004.
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.
