Ballinafad Castle is an Elizabethan blockhouse built during the Nine Years' War by Captain John St. Barbe on land granted to him by King James VI and I. The castle was garrisoned by ten men and commanded by John St. Barbe. It was partially destroyed by Red Hugh O’Donnel in 1595. The castle was again sacked in 1642 and fell out of use by 1680.
Today it is in ruins and is accessible year round. There are no tours, guides, or fees. Visitors can park in a small carpark at the foot of the hill where they will find an interpretive sign. Visitors cannot enter the castle, but the interior is visible through breaches in the walls that are closed off by iron fences.
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.
