Havant is the town in the south east corner of Hampshire, England approximately mid-way between Portsmouth and Chichester. Its borough (population: 125,000) comprises the town and its suburbs including the resort of Hayling Island as well as Rowland's Castle (an exurb), the smaller 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.
Havant has direct railways served by passenger trains to Portsmouth, London and Brighton from Havant railway station. The major A27 road with various crossings sections off the coastal village suburbs of Langstone and the south of Bedhampton. Its north is Leigh Park, a three-ward suburb originally of council housing laid out before 1960 through the cooperation of the local and Portsmouth authorities (the other designated area being Paulsgrove occupying west Cosham), beyond which is Staunton Country Park in the South Downs National Park. To the east is Emsworth, a much smaller contiguous town. To the west is Portsdown Hill and part of Bedhampton. The A3(M) passes to the west. 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, its part closest to the Brighton-Worthing-Littlehampton conurbation.
