The present Dromore Cathedral was originally constructed in 1661 by Jeremy Taylor, Bishop of Down and Connor and has been several times expanded to its present size.
The first church on the site was a wattle and daub building constructed by St Colman circa 510. This was replaced by a medieval church which was destroyed in the late 16th century. The church was again rebuilt and in 1609 elevated to the 'Cathedral Church of Christ the Redeemer' by Letters Patent of James I. In 1641 this building, too, was destroyed.
The present building was first constructed under Bishop Jeremy Taylor in 1661 as a narrow church 100 feet (30 metres) long. In 1811 Thomas Percy (bishop of Dromore) added a short aisle at right angles to the nave to form an L-shaped floor plan. In 1870 a semicircular sanctuary and organ aisle were added. Finally in 1899 an additional aisle parallel to the original nave aisle was added to achieve a conventional rectangular floor plan.
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.
