San Lorenzo is a Baroque-style Roman Catholic church building in Melfi. The octagonal church was initially built in the 1000s by the Byzantine rulers of the city, and was soon occupied by canons belonging to the nearby Abbey of Monticchio. In 1500, it became a parish church.
The church has suffered damage over the centuries from the earthquakes. The present portal and long stairs appears to date to the 17th century. The adjacent bell-tower, rebuilt in the 14th century by the family of Niccolo Acciaiuoli, has since collapsed, and only the base remains. In 2015, the church underwent refurbishment including demolishing a parish house built to the left of the entrance portal.
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.
