Alchester^[1] is the site of an ancient Roman town. The site is not included in any ancient references; hence, the Roman name is not known. However, Eilert Ekwall contended that it appears as Alavna in the Ravenna Cosmography, with the addition of the Old English ceaster to signify a Roman fort.^[2] It lies about 2 miles (3 km) south of Bicester, in the northwest corner of the civil parish of Wendlebury in the English county of Oxfordshire.^[3]

Alchester had a strategic location in Roman Britain at a crossroads on the Silchester – Dorchester on Thames – Towcester road and the Cirencester – St Albans road (Akeman Street). Recent excavations have shown that it was the site of one of the earliest legionary fortresses in Roman Britain after the invasion of 43 AD.

The site has been the subject of investigation since 1996, firstly under the auspices of Oxford University Archaeological Society, then under those of the University of Leicester and the University of Edinburgh.^[4]^[5]

History

Archaeology has revealed that there was an Iron Age settlement close to the later Roman town, and that Roman occupation of the site began in the Claudian period in the form of a fort soon after the invasion of Britain in 43 AD.

Military phase

From the time of the Roman invasion Alchester was in a strategic position in the border region of the Catuvellauni and Dobunni tribes, and in an ideal position to exercise control over wide areas.^{[ citation needed ]}

During the first few years after the invasion, a large legionary fortress of the Legio II Augusta commanded by Vespasian was built here. Alchester was situated behind the early military front line of the Fosse Way in an ideal position as a supply base.^[6]

After the conquest of most of the rest of Roman Britain, the legion moved to Exeter before AD 68 and abandoned the fortress.^{[ citation needed ]}

Civilian era

The town continued to grow, helped by its location at a road junction. Walls were built around the town during the turbulent times of the late 3rd century.

After the 5th century the place was deserted.^[7]

Archaeology

The Legionary Fortress

Playing-card-shaped enclosures with ditches were shown on aerial photographs taken in 1943–45.^[6] Excavations in 1990 focussed initially on the Roman military enclosure near and under the later Roman town, and then on its fortified annex. This proved that the larger enclosure was surrounded by an army-style V-shaped ditch, characteristic of a fort.^[6]

The spread in time and frequency of early objects and the buildings shows that the fort was more substantial than a vexillation camp, and existed for a longer time than a temporary camp for use only during the invasion.^{[ citation needed ]}

Investigation of the gate of the annex revealed two wooden gateposts preserved in waterlogged conditions; dendrochronology gives each of them a felling date of between October AD 44 and March AD 45.^[8] The main fortress must have been built earlier, probably in the year of invasion, 43 AD.

The smaller enclosure, with its U-shaped ditch and square corners was atypical for Roman forts, and was interpreted as a parade ground. Parallels for this have been found associated with legionary fortress of Lambaesis (Algeria), as well as at Tomen y Mur (Gwynedd).^[6] The presence of this would also support the idea of a fairly permanent military base.

The discovery in 2003 of smashed fragments of the tombstone of Lucius Valerius Geminus, a veteran of the Legio II Augusta ^[4] is significant in that it shows he retired from the legion while stationed at Alchester even though he came from north-west Italy and lived in the vicinity until his death. The fortress must have been well-established and probably associated with a nearby vicus.

The inscription reads:

Dis Manibus/ L(ucius) Val(erius) L(uci filius) Pol(lia tribu) Gemi/nus For(o) ♠Germ(anorum)/ vet(eranus) Leg(ionis) [I]I Aug(ustae)/ an(norum) L h(ic) s(itus) e(st)/ he(res) c(uravit)/ e(x) t(estamento)

"To the souls of the departed: Lucius Valerius Geminus, the son of Lucius, of the Pollia voting tribe, from Forum Germanorum, veteran of the Second Augustan Legion, aged 50(?), lies here. His heir had this set up in accordance with his will."

The size of the fort at 14-15ha including the annex is larger than that estimated for the previous fortress of Legio II Augusta at Strasbourg. Other finds also support the conclusion that this was its legionary fortress soon after invasion of Britain and before it moved to Exeter, and that its commander Vespasian was located here rather than in southern England at this time.^[4]

Evidence from coins found at the site suggest abandonment was likely to have taken place before the death of Emperor Nero in AD 68.^[8]

The Town

Outside the western defences, excavation in 1766 of what was then a prominent mound known as the Castle uncovered a sizable Roman bath.^[7]

Excavations in 2003 of the town wall near the west gate showed this had been robbed of building stone in post-Roman times, except for two stones that were found in situ and the wall's rubble foundations.^[4]

The area bounded by defences, about 10 hectares (25 acres), is almost square, with the earliest defences consisting of a gravel rampart and one or more ditches; later, a stone wall was added to the rampart. The dating of these two phases is obscure.^[7]

The planning of streets approaches a rectangular grid, uncommon in smaller Romano-British towns. Along the main street, aerial archaeology has revealed a number of narrow, rectangular strip buildings. Near the centre of the town lay a building with a central court, surrounded by a portico on three sides.^{[ citation needed ]}

The Roman conquest of Britain was the Roman Empire's conquest of most of the island of Britain, which was inhabited by the Celtic Britons. It began in earnest in AD 43 under Emperor Claudius, and was largely completed in the southern half of Britain by AD 87, when the Stanegate was established. The conquered territory became the Roman province of Britannia. Attempts to conquer northern Britain (Caledonia) in the following centuries were not successful.

The legion appears to have still been in existence in the 5th century AD. Its symbol was the lion.

Viroconium or Uriconium, formally Viroconium Cornoviorum, was a Roman city, one corner of which is now occupied by Wroxeter, a small village in Shropshire, England, about 5 miles (8 km) east-south-east of Shrewsbury. At its peak, Viroconium is estimated to have been the 4th-largest Roman settlement in Britain, a civitas with a population of more than 15,000. The settlement probably lasted until the end of the 7th century or the beginning of the 8th. Extensive remains can still be seen.

The site is a scheduled monument.

<span class="mw-page-title-main">Deva Victrix</span> Roman fort built mid 70s AD

Deva Victrix, or simply Deva, was a legionary fortress and town in the Roman province of Britannia on the site of the modern city of Chester. The fortress was built by the Legio II Adiutrix in the 70s AD as the Roman army advanced north against the Brigantes, and rebuilt completely over the next few decades by the Legio XX Valeria Victrix. In the early 3rd century the fortress was again rebuilt. The legion probably remained at the fortress until the late 4th or early 5th century, upon which it fell into disuse.

Caerleon Roman Fortress and Baths encompass the archaeological ruins and sites of the Legionary Fortress of Isca Augusta spread across the town of Caerleon, near the city of Newport, South Wales. Notable for being one of only three permanent legionary fortresses from Roman Britain, Caerleon has provided a unique opportunity to study the archaeology of a Roman Legionary fortress, less affected by the medieval and subsequent urban activity of most such fortresses. Having attracted the attention of eminent archaeologists throughout the 20th century it now has four major public archaeological venues, including the museum run by Cadw, called 'Caerleon Roman Fortress and Baths', featuring the excavated fortress bath-house. Also open to the public is the most complete excavated amphitheatre in Britain, a series of barracks and the National Roman Legion Museum. The fortress and its surrounding civil settlement have been the subject of continuing major archaeological investigations into the 21st century.
