SOUTHWICK, a parish in the hundred of PORTSDOWN, Portsdown division of the county of SOUTHAMPTON, 3 miles (N. E. by E.) from Fareham, containing 711 inhabitants. The living is a donative, in the patronage of T. Thistlethwayte, Esq. The church is dedicated to St. James. A priory of Black canons, founded by Henry I., and originally established at Porchester, in 1133, was soon after removed hither, and flourished till the dissolution, when its revenue was valued at £314. 17. 10. per annum; it acquired some historical celebrity from its having been the scene of the marriage of Henry VI., with Margaret of Anjou; and there are still some small remains of the monastic buildings in Southwick Park. The manor-house is a large building of some antiquity, having two wings terminating in gables, and embattled. King Charles I. was on a visit to the owner of this mansion at the time when the Duke of Buckingham, whom he had accompanied thus far from London, was assassinated by Felton, at Portsmouth; George I. was also entertained here. The publicans at Southwick enjoy the peculiar privilege, under a charter of Queen Elizabeth, of having no soldiers billeted upon them, nor quartered in their houses. A fair for horses is held on April 5th; and here was formerly a market, granted to the priory, in 1235, but it has long been disused.
