Anderitum (also Anderida or Anderidos) was a Saxon Shore fort in the Roman province of Britannia. The ruins adjoin the west end of the village of Pevensey in East Sussex, England. The fort was built in the 290s and was abandoned after it was sacked in 471 (491 according to the disputed Anglo-Saxon Chronicles). It was re-inhabited by Saxons and in the 11th century the Normans built a castle within the east end of the fort.

Gariannonum, or Gariannum, was a Roman Saxon Shore fort in Norfolk, England. The Notitia Dignitatum, a Roman Army "order of battle" from about AD 400, lists nine forts of the Saxon Shore in south and east England, among which one was called Gariannonor. It has been much discussed over the years in terms of spelling (Gariannonum, Garianonum, Gariannum), purpose (whether it really was intended for defence against Saxon raids), and location (whether it was Burgh Castle or the Caister-on-Sea site). The fort is listed as being commanded by the Praepositus equitum stablesianorum, implying its garris
