On top of the Říp Mountain is a romanesque rotunda of Saint George, which is one of the oldest buildings in the Czech Republic. This is mentioned for the first time in 1126, when Soběslav I, Duke of Bohemia, commemorating his victory at the Battle of Chlumec, where he defeated Holy Roman Emperor Lothair III, had the rotunda repaired and extended by the western circular tower. The rotunda's current appearance is the result of a purist reconstruction during the 1870s.
Inside the rotunda is a stone sculpture by contemporary Czech artist Stanislav Hanzík 'The Good Shepherd' from 1979, symbolising the arrival of Czech ancestors to the country and the beginning of Czech history there.
Near the rotunda is a tourist hut that was built in 1907 and still serves travellers today.
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.
