デヴォンポート海軍基地
Since 1650, the City of Plymouth has grown to become the largest city in Devon, mainly due to the naval base at Devonport. Her Majesty's Naval Base (HMNB) Devonport is one of three operating bases in the United Kingdom for the Royal Navy. HMNB Devonport is now the largest naval base in Western Europe. The large Portland Harbour, built at the end of the 19th century and protected by Nothe Fort and the Verne Citadel, was for many years, including during the wars, another of the largest Royal Navy bases.
