In Britain ''.
Bodleian Library, Oxford. The nine forts mentioned in the
Notitia Dignitatum for Britain are listed here, from north to south, with their garrisons. It was garrisoned by the
Equites Dalmatae Brandodunenses, although evidence exists suggesting that its original garrison was the
cohors I Aquitanorum. •
Gariannonum (
Burgh Castle,
Norfolk). Established between 260 and the mid-270s to guard the
River Yare (
Gariannus Fluvius), it was garrisoned by the
Equites Stablesiani Gariannoneses. Although there is some discussion as to whether this is actually the fort at
Caister-on-Sea, and being on the opposite bank of the same estuary as Burgh Castle. •
Othona (
Bradwell-on-Sea,
Essex). Garrisoned by the
Numerus Fortensium. •
Regulbium (
Reculver,
Kent). Together with Brancaster one of the earliest forts, built in the 210s to guard the
Thames estuary, it is likewise a
castrum. It was garrisoned by the
cohors I Baetasiorum since the 3rd century. •
Rutupiae (
Richborough,
Kent), garrisoned by parts of the
Legio II Augusta. •
Dubris (
Dover Castle,
Kent), garrisoned by the
Milites Tungrecani. •
Portus Lemanis (
Lympne,
Kent), garrisoned by the
Numerus Turnacensium. •
Anderitum (
Pevensey Castle,
East Sussex), garrisoned by the
Numerus Abulcorum. •
Portus Adurni (
Portchester Castle,
Hampshire), garrisoned by a
Numerus Exploratorum. There are a few other sites that clearly belonged to the system of the British branch of the Saxon Shore (the so-called "
Wash–
Solent limes"), although they are not included in the
Notitia, such as the forts at
Walton Castle, Suffolk, which has by now sunk into the sea due to erosion, and at
Caister-on-Sea in
Norfolk. In the south,
Carisbrooke Castle on the
Isle of Wight and
Clausentum (
Bitterne, in modern
Southampton) are also regarded as westward extensions of the fortification chain. Other sites probably connected to the Saxon Shore system are the sunken fort at
Skegness, and the remains of possible signal stations at
Thornham in Norfolk,
Corton in Suffolk and
Hadleigh in Essex. Further north on the coast, the precautions took the form of central depots at
Lindum (
Lincoln) and
Malton with roads radiating to coastal signal stations. When an alert was relayed to the base, troops could be dispatched along the road. Further up the coast in North Yorkshire, a series of coastal watchtowers (at
Huntcliff,
Filey,
Ravenscar,
Goldsborough, and
Scarborough) was constructed, linking the southern defences to the northern military zone of the Wall. Similar coastal fortifications are also found in
Wales, at
Cardiff and
Caer Gybi. The only fort in this style in the northern military zone is
Lancaster, Lancashire, built sometime in the mid-late 3rd century replacing an earlier fort and extramural community, which may reflect the extent of coastal protection on the north-west coast from invading tribes from Ireland.
In Gaul The
Notitia also includes two separate commands for the northern coast of Gaul, both of which belonged to the Saxon Shore system. However, when the list was compiled, in , Britain had been abandoned by Roman forces. The first command controlled the shores of the province
Belgica Secunda (roughly between the estuaries of the
Scheldt and the
Somme), under the
dux Belgicae Secundae with headquarters at Portus Aepatiaci: •
Marcae (unidentified location near
Calais, possibly
Marquise or
Marck), garrisoned by the
Equites Dalmatae. In the
Notitia, together with
Grannona, it is the only site on the Gallic shore to be explicitly referred to as lying
in litore Saxonico. •
Locus Quartensis sive Hornensis (probably at the mouth of the
Somme), the port of the
classis Sambrica ("Fleet of the Somme") •
Portus Aepatiaci (possibly
Étaples), garrisoned by the
milites Nervii. Although not mentioned in the
Notitia, the port of
Gesoriacum or
Bononia (
Boulogne-sur-Mer), which until 296 was the main base of the
Classis Britannica, would also have come under the
dux Belgicae Secundae. To this group also belongs the Roman fort at
Oudenburg in Belgium. Further west, under the
dux tractus Armoricani et Nervicani, were mainly the coasts of
Armorica, nowadays
Normandy and
Brittany. The
Notitia lists the following sites: •
Grannona (disputed location, either at the mouths of the
Seine or at
Port-en-Bessin), the seat of the
dux, garrisoned by the
cohors prima nova Armoricana. In the
Notitia, it is explicitly mentioned as lying
in litore Saxonico. The location of the Roman stronghold of Grannono/Grannona may have been located within or near the boundary of Brittany - see
Guérande. •
Rotomagus (
Rouen), garrisoned by the
milites Ursariensii •
Constantia (
Coutances), garrisoned by the
legio I Flavia Gallicana Constantia •
Abricantis (
Avranches), garrisoned by the
milites Dalmati •
Grannona (uncertain whether this is a different location than the first
Grannona, perhaps
Granville), garrisoned by the
milites Grannonensii •
Aleto or
Aletum (Aleth, near
Saint-Malo), garrisoned by the
milites Martensii •
Osismis (
Brest), garrisoned by the
milites Mauri Osismiaci •
Blabia (perhaps
Hennebont), garrisoned by the
milites Carronensii •
Benetis (possibly
Vannes), garrisoned by the
milites Mauri Beneti •
Manatias (
Nantes), garrisoned by the
milites superventores In addition, there are several other sites where a Roman military presence has been suggested. At
Alderney, the fort known as "The Nunnery" is known to date to Roman times, and the settlement at Longy Common has been cited as evidence of a Roman military establishment, though the archaeological evidence there is, at best, scant. ==In popular culture==
