context_page_description: 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.
context_section_description: Pevensey Castle was established as one of the nine Late Roman forts on the British side of the Saxon Shore (Latin: Litus Saxonicum). The fort is named as Anderitum, apparently meaning "great ford", in the Notitia Dignitatum, a list of Roman "dignities" (i.e. public offices) as of the 5th century. (An alternative spelling of Anderida or Anderita has also been proposed, but is disfavoured.)
  The fort was long thought to have been built in the mid-4th century but it has been dated to around 290, based on the dating of wooden piles which were found underpinning the Roman walls in an excavation carried out in 1994. Other Saxon Shore forts were built or reconstructed around this time as part of a systematic programme of improvements to the coastal defences of Roman Britain. The construction of the Saxon Shore forts has been linked to the raids that Saxon and  Jute pirates (from what is now northern Germany and mainland Denmark) were mounting against communities along the North Sea and English Channel. An alternative explanation is that Anderitum was built to defend Roman Britain from Rome itself. Carausius, a Roman general who commanded the Classis Britannica (the Roman fleet based in the English Channel), revolted against Rome in 286 and declared himself emperor of Britain and northern Gaul. He was assassinated in 293 by his treasurer, Allectus, who was himself killed in 296 when the Roman emperor Constantius Chlorus invaded Britain to overthrow the usurper.
  Coins of both Carausius and Allectus have been discovered buried in the foundations of the fort's walls. A later coin of 330–335 was found under a tower in the 1930s, suggesting that the fort may have undergone a major repair or reconstruction around that time. The usurpers had inherited an existing system of coastal defence – the earlier Saxon Shore forts – and may have decided to augment it with the construction of Pevensey Castle and its close contemporary, Portus Adurni (Portchester Castle).
  Anderitum appears to have been a particularly important link in the Saxon Shore forts, which extended from Hampshire to Norfolk and may have been connected by intermediate watchtowers. The Notitia Dignitatum mentions a fleet that was presumably based there, the Classis Anderidaensis. It would probably have acted in coordination with naval units based on the other side of the Channel to intercept pirate ships passing through the Channel. Like the other Saxon Shore forts, Anderitum's position at a strategic harbour would have enabled the Romans to control access to the shoreline and prevent invaders from penetrating inland. It was linked by a road built in the late Roman period, probably at the same time as the fort.
