The most important British naval station, a seaport and market-town, is situated on Portsea Island, on the coast of Hants, 15 m. SE. of Southampton. It is an unimposing town, but strongly fortified. St. Thomas's and Garrison Chapel are old churches with historical associations. The naval dockyards contain 12 docks lined with masonry, vast store-houses, wood-mills, anchor-forges, and building-slips. Some of the docks are roofed over, as also is a large building-slip on which four vessels may be constructed at once. The harbour can receive the largest war-vessels, and in Spithead roadstead 1000 ships can anchor at once. The trade of Portsmouth is dependent on the dockyards. It owes its defences to Edward IV. Elizabeth, and William III. It was the scene of Buckingham's assassination and of the loss of the Royal George. Three novelists were born here—Dickens, Meredith, and Besant.
