Siege of Pevensey Castle (1088)
History & Significance
Pevensey Castle is a medieval castle and former Roman Saxon Shore fort at Pevensey in the English county of East Sussex. The site is a scheduled monument in the care of English Heritage and is open to visitors. Built around 290 AD and known to the Romans as Anderitum, the fort appears to have been the base for a fleet called the Classis Anderidaensis. The reasons for its construction are unclear; long thought to have been part of a Roman defensive system to guard the British and Gallic coasts against Saxon pirates, it has more recently been suggested that Anderitum and the other Saxon Shore forts were built by a usurper in an ultimately unsuccessful attempt to prevent Rome from reimposing its control over Britain.
Anderitum fell into ruin following the end of the Roman occupation but was reoccupied in 1066 by the Normans, for whom it became a key strategic bulwark. A stone keep and fortification was built within the Roman walls and faced several sieges. Although its garrison was twice starved into surrender, it was never successfully stormed. The castle was occupied more or less continuously until the 16th century, apart from a possible break in the early 13th century when it was slighted during the First Barons' War. It had been abandoned again by the late 16th century and remained a crumbling, partly overgrown ruin until it was acquired by the state in 1925.
Pevensey Castle was reoccupied between 1940 and 1945, during the Second World War, when it was garrisoned by units from the Home Guard, the British and Canadian armies and the United States Army Air Corps. Machine-gun posts were built into the Roman and medieval walls to control the flat land around Pevensey and guard against the threat of a German invasion. They were left in place after the war and can still be seen today. Pevensey is one of many Norman castles built around the south of England.
Pevensey Castle was constructed by the Romans on a spur of sand and clay that stands about 10 metres (33 ft) above sea level. In Roman times this spur was a peninsula that projected into a tidal lagoon and marshes, making it a strong natural defensive position. A harbour is thought to have been situated near the south wall of the castle, sheltered by a long spit of shingle where the village of Pevensey Bay stands now. A small river, Pevensey Haven, runs along the north side of the peninsula and would originally have discharged into the lagoon, but is now largely silted up.
Since Roman times, silting and land reclamation in the Pevensey Levels have pushed the coastline out by about 1.5 kilometres (0.9 mi), leaving the castle landlocked. The land between the castle and the sea is now a flat marshland drained by a network of ditches and sewers or field drains. The modern village of Pevensey is situated mostly to the east of the castle, at the end of the ancient peninsula. Castle Road (the B2191) curves around the Roman north wall and connects Pevensey to the nearby village of Westham. A public footpath crosses the interior of the castle, linking the two villages. An area of reclaimed land, formerly part of the Pevensey tidal lagoon but now marshland and fields crossed by the Eastbourne to Hastings railway line, is situated immediately to the south of the castle.
The ground they fought on
The site of Siege of Pevensey Castle (1088) lies on Wealden Group, bedrock that formed in the Barremian. The rock here is sandstone and siltstone, interbedded.
The most striking feature of Pevensey in any siege was its extraordinary natural and man-made strength. The Roman curtain walls, still standing up to 8.2 metres high and 4.2 metres thick at the base, enclosed an area of over nine acres, and the peninsula on which the castle stood was flanked by tidal lagoon and marshes, making a direct assault exceptionally hazardous. Any besieger in 1088 would have faced one of the most formidable defensive positions in southern England.
