The Lancken-Granitz dolmens are a group of seven megalith tombs in the Lancken-Granitz municipality on Rügen. Erected during the middle Neolithic, when they were used by the Funnelbeaker culture, at least some were in use until the early Bronze Age. Three of them are encircled by solitary rocks forming either rectangles or a stone circle, one has a solitary 'guardian stone' on its eastern side.
The dolmens were constructed from glacial erratic boulders and red sandstone. In part subdivided into up to four compartments as common for the region, one dolmen showed a subdivision into six such compartments, which is an unusually high number. When the tombs were archaeologically assessed in 1969, Stone and Bronze Age funerary goods were retrieved, including flint hatches, stone axes, amber pearls, bronze needles and necklaces as well as an abundance of arrowheads and pottery.
The dolmens are part of a series built between 3,500 and 3,200 BC, during the Neolithic. As of 2001, about 400 of those are preserved in Mecklenburg-Vorpommern, 55 of which are located on the isle of Rügen. Initially their number had been much larger, but many were destroyed when their boulders were used for church, housing and street construction since the Middle Ages. In the 20th century, local teacher Friedrich-Wilhelm Furthmann and his wife preserved the dolmens in the Lancken-Granitz and Burtevitz area, before they were excavated by archaeologist Ewald Schuldt in 1969 and immediately thereafter restored for touristic use. This was part of a series of 106 excavations conducted by Schuldt's team on megalith sites in present-day Mecklenburg-Vorpommern between 1964 and 1972.
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.
