The European Archaeological Park at Bliesbruck-Reinheim, in the German municipality of Gersheim and the French municipality of Bliesbruck, is a cross-border project which combines excavations and reconstructions of Celtic and Roman finds with exhibition and educational facilities. It was created in 1989 as a result of the archaeological work being done on both sides of the Franco-German border. Together with archaeological evidence from the Mesolithic Period, the Bronze Age, and the period of the Germanic migrations, the Celtic and Roman finds from the Iron Age bear witness to a history of continuous settlement in the Blies Valley that spans a period of 10,000 years.
Probably the most interesting excavation on the area is the Tomb of the Celtic Princess of Reinheim, dating from the 4th century BC. It is a woman's grave that was filled with exceptionally rich funerary objects. The burial chamber, constructed of oaken beams, was covered over by a massive mound of earth.
There is also a Roman villa in Reinheim. This very large complex includes courtyard walls enclosing an area 300 metres long and 135 metres wide with a main building to the north that measures almost 80 by 62 metres. One portion of the building in the north end of the west wing is thought to have been the villa's private thermal baths, due to the layout of its rooms and the discovery of water channels and fragments of cylindrical tiles (tubuli) attesting to the existence of under-floor heating (hypocaust).
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.
