U 12

Scotland's National Record of the Historic Environment records U 12 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 12 was a British Royal Navy E-class submarine lost in 1915 during the First World War, likely due to a mine or accident off the Scottish coast. No lives were lost, and the wreck is considered historically significant as an example of early 20th-century submarine technology.
