The eastern part of the 400 metre-long Husovo Square in Rakovník is dominated by the high Gothic Church of St. Bartholomew, a 14th-century structure. The church was built on the site of an older church dedicated to St. Nicholas. Adjacent to the church stands a bell tower dating from 1495. It is considered as the most precious gothic bell tower in the Czech Republic and one of the most precious in Europe. The bell has a diameter of 1.6 metres.
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.
