Rochester, a city of Kent, 29 miles ESE. of London, lies chiefly on the right bank of the tidal Medway, continuous with Chatham, and joined to Strood by an iron swing bridge, constructed in 1850-56 at a cost of £170,000. The castle or keep, which crowns a steep eminence near the bridge, was the work of Archbishop William de Corbeuil (1126); but the wall overlooking the river contains Norman masonry of earlier date, built upon Roman foundations. It is 104 feet high and 70 feet square, with walls 12 feet thick, and is a very fine specimen of Norman architecture; it was taken by John (1215, the south-east corner being rebuilt shortly afterwards), vainly attacked by De Montfort (1264), and taken again by Tyler (1381). Both castle and grounds were purchased in 1883 by the corporation from the Earl of Jersey. The episcopal see was founded in 604 by St Augustine, and the foundations of the cathedral then built have lately been discovered. Bishop Gundulf (1077-1107) built a new cathedral, of which part of the crypt remains. This cathedral was rebuilt by Ernulf and John of Canterbury (1115-37), whose nave remains; and the choir was again rebuilt and enlarged in the 13th century in part out of offerings of pilgrims at the shrine of St William of Perth, a Scotch baker, who, on a pilgrimage to the Holy Land, was murdered near Chatham by his companion and adopted son; the tower rebuilt by Cottingham (1825-26), the choir and transepts restored by Scott (1871-77), and the west front being restored by Pearson in 1891. It measures 306 feet in length, and has double transepts; and special features of interest are the Norman west doorway and nave, the Early English choir, of singular plan and early character, the spacious crypt, and a fine Decorated doorway leading to the modern library. The ruins of an early Norman keep or residence (?) built by Gundulf, the architect of the Tower of London, stand on the north side of the choir. Of Rochester's bishops since 604, some eighty in number, may be mentioned Paulinus (previously first bishop of York), Gundulf, Walter de Merton, Fisher, Ridley, Atterbury, and Horsley. St Bartholomew's Hospital, founded by Gundulf in 1078 for lepers, was refounded in 1863; the Norman chapel remains. Watts' Charity House, founded in 1579 to lodge 'six poor travellers, not being rogues or proctors,' has been immortalised by Dickens, whose home, Gadshill (q.v.), is 3 miles distant, and who introduces Rochester into Pickwick, Edwin Drood, and others of his novels. Three schools are the cathedral grammar-school (Henry VIII.), Williamson's mathematical school (1701; reopened under a new scheme, 1880), and a grammar-school for girls (1888); and other buildings are Satis House, Restoration House (Charles II. slept here in 1660), the guild-hall (1687), and the corn exchange (1871). Rochester—the Roman station Durobrivæ and Anglo-Saxon Hrofe-ceastre—was made a municipal borough by Henry II. It lost one of its two members in 1885. James II. embarked here in his flight (1688). Pop. (1851) 16,508; (1871) 18,352; (1891) 26,170.
