Château Saint-Léon is a former castle in the center of Eguisheim. The castle was built by the Counts of Eguisheim and taken over by the Bishop of Strasbourg during the 13th century. An episcopal bailiff occupied it until the French Revolution (1789). The enceinte was surrounded by a moat which was filled in by the 18th century. Houses built in the castle courtyard and against its walls were destroyed by a fire in 1877 which also damaged the castle - it was left in runs for many years.
In 1885, it was bought by the Bishop of Strasbourg through the mediation of a M. Stumpf who wanted to build a chapel dedicated to Saint Leo. The remains of the keep were destroyed and the chapel built in its place, the works being carried out by the architect of historic monuments, Charles Winkler. The chapel was completed in 1895. Winkler also restored the residence at the south of the site which had been rebuilt, with mullioned windows in the 16th century. He added a staircase turret and a neo-Renaissance balcony.
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.
