Details

The Hilsea Lines are a line of 18th- and 19th-century fortifications built to protect the northern approach to Portsea, an island off the coast of England which is part of the city of Portsmouth and its key naval base. They are now used as a greenspace and leisure area.Natural defencesThe island is separated from the mainland by a narrow stretch of water called Portsbridge Creek. The first means of crossing the creek was by stepping stones, followed by a single track bridge, built to allow the passage of pedestrians and horse-drawn carts to have access to Portsea Island.Early defencesEarly defences were focused on the 'Portsbridge' that crossed the creek. A fortification is thought to have been built at the mainland end of the bridge during the reign of King Henry VIII. In 1642 the fort was captured by parliamentary forces as part of the English Civil War. It was rebuilt in 1688 and again in 1746. During the Civil War further defences were constructed by the royalists consisting of a wooden barricade mounted on the bridge backed by a small fort equipped with 4 cannon. The cannon were withdrawn on 10 August 1642 and with the barricade held by as few as eight men the parliamentarian forces were able to cross the creek two days latter. The Parliamentarians then constructed their own defences of at the site of the bridge consisting of two mounds on which a total of 6 cannon were mounted. The Parliamentarians appear to have constructed further defences near the bridge in 1643.The first linesDuring 1756 and 1757 defensive lines were constructed on the Portsea Island side of the creek under the supervision of John Peter Desmaretz. They consisted of a 15- and 6ft ditch backed by a 7- rampart. Water could be allowed to flow into the ditch from sluices at either end.
