The original Gothic castle of Grabštejn (or Grafenstein) was founded in the 13th century. In 1562, it was bought by Crown Chancellor Georg Mehl von Strelitz. Between 1566 and 1586, he had rebuilt the castle in Renaissance style and thus turned it into a representative chateau.
Georg Mehl also had a steward's house built below the castle, which was around the year 1830 rebuilt in Classicist style. Shortly before that – around 1818 – Christian of Clam-Gallas had built the New Castle near the Old Castle. The new building was surrounded by a large garden with a number of valuable plants. The Old Castle has preserved its original Renaissance appearance despite a fire which damaged its upper floors in 1843.
The House of Clam-Gallas owned Grabštejn since 1704 until it was confiscated in 1945. After the Second World War, the castle was open to the public, but in 1953, the whole castle complex was taken over by the Ministry of Defence. The Old Castle's condition significantly deteriorated after the army left in the late 1980s.
Repairs and restorations began in 1989. Nowadays, Grabštejn is one of the best restored monuments of great importance in the Czech Republic. The castle was opened to the public again in 1993. The tower offers a marvellous view of the three-border-triangle, the castle's northern wing, and the vault. The most touristically attractive part of the castle interior is the St. Barbara chapel decorated with Renaissance fresco paintings from the 16th century. All parts of the ceiling and walls are ornamented in with interlaced figural, animal, and heraldic motifs.
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.
