Buccleuch Dock is one of the four docks which make up the Royal Port of Barrow in Barrow-in-Furness, England. It was constructed between 1863 and 1872 to the same specification as the attached Devonshire Dock - the docks having been separated by a bridge for most of their lifetime. Buccleuch Dock covers 125,000 square metres (1,350,000 sq ft) and was named after the 5th Duke of Buccleuch, who invested heavily in Barrow's public services during the late 19th century. Buccleuch Dock is owned by Associated British Ports and is also used by BAE Systems where the majority of the shipyard's surface vessels are docked for fitting out.
