U 40

Scotland's National Record of the Historic Environment records U 40 as Submarine (first World War)-(1915). The official map says its point is accurate as follows: NGR given to the nearest 1m. The record does not by itself mean that the public may enter the place.

U 40 was a German U-boat (submarine) of the Imperial Navy, active during the First World War. It was lost in 1915, likely due to mine damage or collision, though no detailed records of casualties or cargo are known; its significance lies in representing Germany's naval presence in Scottish waters during the early stages of the war.
