Langstone is a village near Havant, Hampshire in the south east of England in Portsmouth. It has good railway connections to London, Southampton, Portsmouth and Brighton, from the nearby Havant railway station. There are many large gated detached houses on the main road, "Langstone Road" and on the roads surrounding this. It has a sailing club, several architecturally unusual buildings, and several historically significant buildings, including a converted (water) millhouse and a converted 18th century windmill, the latter of which is a local landmark. Geography The village surrounds "Langstone Road" which leads to Hayling Island. There is a technology park on Langstone Road and this is due to the connections of the road. It lies just off the A27 that provides quick links to Portsmouth, Southampton and Brighton. The A3(M) to London is also nearby and the distance to the M25 is about 45 miles. It is connected by Langstone Bridge, a single-carriageway road and footbridge, to Hayling Island to the South; this road (the A3023) is the only road connection from Hayling Island to the mainland. To the west of the road bridge the remains of the former railway bridge are visible; Langstone Harbour lies to the west of the railway bridge, Chichester Harbour to the east. The historic causeway to Hayling Island known as the Wadeway still exists, however it is now completely impassable, having been cut in two by a deep channel for the Portsmouth and Chichester Canal in the 1820s, the same company having subsequently funded the old wooden road bridge, served by a toll-house situated at the northern end. There was a weight-limit and after WW2 only single-decker buses were allowed across and if they were carrying too many passengers some had to get out and walk, regardless of the weather, to reduce axle-weight. The old wooden bridge was demolished following construction of the current (2014) concrete bridge in the late 1950s. The much earlier causeway was known as the wade way, and was classified as a bridleway in 1988, and is shown as such on modern Ordnance Survey maps in spite of its use being considered hazardous at best. Excavation of this feature in 2006, constructed on a natural high point in the harbour, put its date in the Roman to mediaeval range but found no evidence to be more specific. The village High Street is designated as a Conservation Area (denoted by a
