Tynemouth (Tin'muth), the chief watering-place of Northumberland, 9 miles E. of Newcastle, occupies the angle formed by the line of the coast and the Tyne. The municipal and parliamentary borough comprises the townships of Tynemouth, North Shields (q.v.), Chirton, Cullercoats, and Preston, Edwin, King of Northumbria, founded here, about 627, a church of wood; King Oswald rebuilt it of stone about 640, and probably established the monastery, which suffered much from the Danes. It was refounded in 1090 by Mowbray, Earl of Northumberland. The remains of the priory are chiefly those of the church, which was built about 1100 and enlarged about 1220. The chancel, whose eastern and southern walls are still standing, is one of the most exquisite specimens of Early English. The Lady Chapel, a chantry of the Percies, was founded towards the close of the 14th c. Tynemouth castle was built about 1296. All that remains of it now is the great 14th-century gateway. A wide road extends to Cullercoats called the Grand Parade. The sands are nearly a mile long, and the cliffs are very picturesque. The aquarium (1877-78) is now used for promenade concerts. The pier, over 1/2 mile long, was built in 1854-92. On the cliff above it is the lighthouse, 62 feet high. A monument to Lord Collingwood, by Lough, was erected in 1845 on Galley Hill. The borough returns one member. Pop. of township (1881) 22,548; of municipal borough (1891) 46,588; (1901) 51,514. See Gibson's Monastery of Tynemouth (2 vols. 1846).
