a town and parish of England, in the county of Surrey and hundred of Wallington, nine miles south of London. It stands near the source of the river Wandle, and is supposed to be the Norimagus of the Antonine Itinerary, and the Croinedone of Domesday Book. In the neighbourhood there are distinct traces of Roman occupation, and several gold coins bearing the stamp of the later emperors have been found. A cluster of twenty-five tumuli between the town and Addington Park, and a circular encampment with a double moat, form the most interesting portion of the remains. The manor of Croydon, originally presented to Archbishop Lanfranc, remained till within a recent period the residence of the primates of Canterbury; but it is now converted into a factory, and the grounds are used as a bleachfield. The new town of Croydon consists principally of a well-built street stretching along the road to Brighton. The principal buildings are the parish church (containing several sumptuous tombs of the primates) and the town-hall. There are places of worship for the various bodies of dissenters, numerous schools, a literary institute, and an ancient hospital founded by Whitgift. About a mile distant is the East India Company's military college at Aldiscombe. Croydon is the seat of a county court, and of the assizes alternately with Guildford. Its site is remarkable for the number of springs which issue from the soil. One of these, called the "Bounce," bursts forth a short way above the town at irregular intervals of from one to ten years or more; and after running as a torrent for two or three months, it as quickly vanishes. This phenomenon seems to arise from extensive falls of rain over the chalk-hills of the district, which sink into the porous soil and reappear after a considerable interval from crevices at lower levels. Croydon was visited with a remarkably fatal fever in 1852. Pop. 10,260.
