Anderitum (Pevensey)

Fort and Saxon Shore Fort

Anderitum/Anderida – The Place at the River Mouth – Pre-fort occupation was limited in the 1st to 2nd centuries AD, and the stone fort was built in circa 293-300 AD, with military occupation at least until the end of the 4th century. Occupation continued in some form until it was sacked in circa 470 AD by the Saxons.

Classical References to Anderitum / Anderida

The name of the Roman station at Pevensey is first mentioned in the Notitia Dignitatum of the late-4th/early-5th centuries where it appears as Anderide, between the entries for Rutupiae (Richborough, Kent) and Portus Ardaoni (Portchester, Hampshire). It was one of nine forts around the south and east coasts commanded by the Comes Litoris Saxonici per Britanniam, or the ‘Count of the Saxon Shore’.

Whether or not these forts were established as a coherent defensive system is not clear, but some may have had naval detachments, working also with ships based at coastal forts in northern France. The Notitia mentions a fleet, the classis Anderidaensis, which took its name from Anderida.

The Pevensey fort is last mentioned in the Ravenna Cosmology of the seventh century, in which the name is recorded as Anderelio Nuba (R&C#68), between the duplicated entry for Iacio Dulma (Towcester, Northamptonshire) and the unknown station Mutuantonis located somewhere in south-east England.

There is some confusion about the name of the Roman fort. The DOE name plaque, the curator, documentary evidence shown to the investigator by the curator, and the 1952 official guide called it Anderida. Only the OS and the 1970 revised pamphlet call it Anderita.  The name ‘Anderita’ or ‘Anderida’ :- ‘Anderida’ is the traditional name, but Jackson discusses the orthography in detail and concludes (a) … “a Celtic ‘Anderida’ is meaningless, whereas to the eye of the Celticist the correct form is obviously Roman-British ‘Anderitum’ or rather its plural ‘Anderita’, ‘The Great Fords’,” and (b) “It is to be hoped that the unwarranted ‘Anderida’ will be dropped in future, and ‘Anderita’ substituted.” Name ‘ANDERITVM’ accepted for 4th.edition R.B.Map.

The Epigraphy of Anderitum / Anderida

Although there are no inscriptions on stone recorded in Volume I of the R.I.B., many roofing tiles have been unearthed within the Pevensey defenses which have been stamped on the back with one of the oldest Roman texts in Britain (vide infra). They likely record the activities of the last known Roman governor to campaign in Britain, Stilicho the Vandal, who has also been connected with the series of signal stations along the north-eastern coast between Huntcliff in Cleveland and Filey in North Yorkshire. This man was the most favoured general of the emperor Honorius, the younger son of Theodosius, who ruled the Western Empire from his citadel at Ravenna between 395AD and 423 (vide supra).

The Garrison Unit(s) of Anderida

The only record of any of the fort’s garrison units is contained in the Notitia Dignitatum mentioned above, where, included among the forces “at the disposal of the Right Honourable Count of the Saxon shore in Britain” there is the entry for Pevensey shown below.

The Pevensey Entry from the Notitia Dignitatum

Praepositus numeri Abulcorum, Anderidos

“The commander of the Company of Abulci¹ at Anderida

(Notitia Dignitatum xxviii.20; 4th/5th C.)
  1. The Abulci possibly hailed from the Roman town of Abula in Hispania Tarraconensis mentioned by Ptolemy, now known as Avila near Madrid in central Spain. They could equally be a little-known tribe from Germany.

The Saxon Shore Fort

By the mid 7th century occupation had been re-established within the walls. Covering almost 4ha, the fort survives in the form of substantial ruins and buried remains. It is enclosed by a massive defensive wall which was strengthened by irregularly-spaced, externally projecting semicircular bastions. The Middle and Late Saxon occupation includes a possible royal palace, hinted at by a number of luxury objects found on the site.

Pevensey (Fig. 12b) is oval in shape, with an area of over 8 acres. Its walls are 12 feet thick and stand 28 feet high; they are built on a framework of timber sleepers embedded in the surface of a chalk and stone foundation, and have U-shaped bastions and tile bonding-courses. The gates, flanked by towers, are 10 feet wide, and there is a postern curved in such a way that a person entering cannot see into the fort.” (Collingwood, p.53)

By the mid 9th century it had become a small fishing port and a centre of salt production. William the Conquerer landed at Pevensey in 1066, and the Norman army are believed to have made use of the Roman fort as one of their first armed camps.

Other Roman Sites in the Locale

There is a villa at Eastbourne (TV6198), four miles to the south-west along the coast. The Roman pottery kiln at Arlington (TQ5207), lies on the line of the suspected road to the minor settlement at Hassocks, and a substantial Roman building has been found at Newhaven (TQ4401) along the route of the possible coastal road to Brighton and Noviomagus (Chichester).
