The Church of Saint Matthew (San Matteo al Cassaro) was built between 1633 and 1664 by the will of the Miseremini confraternity. The building was probably designed by the architect of the Senate of Palermo, Mariano Smiriglio, but was completed by Gaspare Guercio and Carlo D'Aprile. It is decorated with many works of important Sicilian artists like Vito D'Anna, Pietro Novelli, Giacomo Serpotta, Bartolomeo Sanseverino, Filippo Randazzo, Antonio Manno, Francesco Sozzi. The church is also connected to the palermitan legend of the Beati Paoli.
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.
