The ancient town of La Hoya is an important archaeological site of the Bronze and Iron Ages. The fortified town was inhabited between the 15th and 3rd centuries BCE and occupies four hectares.
In the early period of Middle-Late Bronze Age, the fortifications, as well the houses, were all made of wood. In the Early-Middle Iron Age construction became more complex using mixed formulas with stone, wood and adobe. Most houses were near the wall in this period.
During the Late Iron Age, with a cultural context that some classify as Celtiberian, shows important changes in urbanization: with paved streets and plazas that form a reticular structure. The wall is also rebuilt on stone. This final period also shows great advancement in the technologies: potter's wheel, elaborated blacksmithing, etc.
The successive layers of rubble, that served as cimentations for further edification, make up a small tell 3 meters high.
The town was destroyed violently c. 300 BCE, leaving the remains of the people and their quotidian tools in the streets.
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.
