The Torre of Lapela is a ruined medieval castle located next to the Minho River in the town of Lapela, in Monção municipality.
One tower is all that remains of the Castle of Lapela, which was situated a few kilometers downstream from the Castle of Monção, which defended the ford of the Minho. The historians attribute its foundation to Lourenço Gonçalves de Abreu, lord of Merufe, Sanfins, Lapela, Barbeita, Regalados, and other lands of the Alto Minho. It is thought that because he had fought in the Battle of Valdevez next to King Afonso I and his father, Gonçalo Martins Abreu, Afonso I had the castle built and appointed him its first commander.
Constructed of stone ashlar, the square tower measures 10 meters on a side and 35 meters high. Its walls are three meters thick. It has a single entrance on the north facade about 6 meters above the ground, surmounted with the coat of arms of the Kingdom of Portugal.
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.
