The Church of St Nicholas is a parish church dating from the 13th century. Its exceptional size reflects the importance and standing of the borough of Grosmont at the time of the church's construction and has led it to be called a 'miniature cathedral'.
By the late 19th century the church was close to collapse and was saved through an extensive reconstruction in 1869–79 by J. P. Seddon.
The church is built of Old Red Sandstone with ashlar dressings and slate roofs. It comprises the nave, transepts, the central tower, a chancel, a secondary chapel and a porch.
Largely unaltered from the time of its building, by the 19th century the church had seriously decayed and its tower was close to collapse. It was rescued from dereliction in a restoration.
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.
