Portsmouth is a city on the south coast of England and was once the United Kingdom’s most significant naval port. Situated largely on an island connected to the mainland by bridges, the city has a population of 207,100 and is the mostly densely populated city in the country. Settled since before Roman times, Portsmouth was used as a dock since the late 12th century and is home today to the world’s largest dry dock still in use. Commercial ships used the port but it was primarily the launching pad for the Royal Navy, which still has a major base there. The Historic Dockyard houses some of the world’s most famous naval ships including HMS Warrior, the Mary Rose and HMS Victory, Lord Nelson’s ship, and is a popular visitor attraction. Although not as busy as in its heyday, Portsmouth’s main economy is the dockyard – a tenth of the city’s workforce is employed there. Due to bombardment in World War II, much of the city had to be rebuilt and there are several major housing developments on the outskirts, as well as a new waterfront development at Gunwharf Quays of shops, restaurants, houses and the Spinnaker Tower.
