Templehouse Castle was a rectangular keepless castle, built in 1181 located near the townland of Ballinacarrow on the outskirts of Ballymote. The Temple House lands were granted to the Knights Templar in 1216 and passed to the Knights Hospitaller when the Templars were disbanded in 1311. The castle was converted to a domestic residence in 1627 and besieged and badly damaged in 1641.
Near the castle is Temple House, a Georgian mansion set in a family estate of over 400 ha overlooking the lakeside ruins of a Knights Templar castle and is now a luxury country guest house, like a hotel. Originally built in c. 1825, it was substantially extended and embellished c. 1864.
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.
