Havant ( HAV-ənt) is a town in the south east corner of Hampshire, England approximately midway between Portsmouth and Chichester. Its borough (population: 125,000) comprises the town (45,826) and its suburbs including the resort of Hayling Island as well as Rowland's Castle (an exurb), the larger town of Waterlooville and Langstone Harbour. Housing and population more than doubled under either definition of Havant in the 20 years following World War II, a period of major conversion of land from agriculture and woodland to housing across the region following the incendiary bombing of Portsmouth and the Blitz. The old centre of the town was a small Celtic settlement before Roman times and the town's commerce, retired and commuter population swelled after World War II so as to be usually considered economically part of the Portsmouth conurbation.
