Summary : The site of the Roman fort at Carlisle. Dendrochronology indicates the south defences were constructed in the autumn/winter of AD 72-3. It covered approximately 3.2 hectares, considerably larger than previously thought, and contained many timber buildings. Dendrochronological dating indicates reconstruction of the fort within its defensive perimeter occurred within the autumn/winter of AD 83-4. The fort was demolished in circa AD 103-5, and then rebuilt in timber. The fort was not abandoned following the construction of Hadrian's Wall, but at some point during Hadrian's reign a marked change in occupation occurred, with widespread internal re-planning. This is in all likelihood due to the construction of the fort at Stanwix less than 1km to the north, and the fort at Carlisle subsequently became less of a major military base. The fort was demolished around the middle of the second century, perhaps as a consequence of the Antonine reoccupation of southern Scotland. Widespread silting in the second half the second century is suggestive of abandonment of the fort. A building was erected in the south-east quadrant sometime after AD 165, and was associated with a road. Timber buildings were also present. At some time in the early third century the fort was rebuilt in stone in a conventional form. Few structural changes were made before the fourth century when some remodelling occurred. Occupation continued well into the fifth century. The levelled remains of the fort were covered by 'dark earth', although many walls were probably upstanding for many centuries, and were probably only robbed to ground level in the medieval period. |

The first clear evidence for Roman military occupation of Carlisle came in 1892, when parts of a turf and timber platform, thought to represent an Agricolan fort, were discovered under Tullie House (4). The platform is the base of a building 40 feet wide from north to south, and the known length, not the full length, 220 feet east to west. (See illustration card) (1).
The exact position and limits of the fort are uncertain, but it seems probable from its scale and nature that it was a large fort, restricted by natural limitations up to circa 8 acres, and therefore possibly legionary. The platform has been generally accepted as the base of the northern rampart of a fort, but excavations to the north of this site in Annetwell Street in 1978 located a double portal entrance flanked by projecting towers, recessed into a turf and timber rampart discovered in 1973. (See illustration card). This gateway is now thought to be the southern gateway of the timber fort which extended over the area now occupied by the castle (see NY 35 NE 1.1), and not the Cathedral (see NY 35 NE 45) as previously thought (3).
The fort is of 2 phases. Evidence of the earliest occupation was found during excavations in 1954-6, when 2 pre-Hadrianic levels were discovered. The lowest level is Flavian, and is thought to represent the Agricolan bridgehead fort stage built as the western terminus of the Stonegate (RR 85), and as protection for crossing the River Eden. The second phase is attributed to a Trajanic reconstruction after demolition circa AD 100 (5).
As a result of excavations at Tullie House in 1954 and 1955 it is now known that the early military site was re-planned for civilian use. The 1st century fort was evacuated by the army early in the 2nd century, possibly on the establishment of the wall fort at Stanvix. (6) (1-8)
Finds from the fort site in Annetwell Street include wooden remains of ink writing tablets, a fragment of an unstratified red sandstone altar, measuring 0.40m by 0.36m, a fragment of a red sandstone sculptured relief, measuring 0.12m by 0.15m by 0.09m and two carved heads, interpreted as Genii, depicting figures wearing mural crowns.

A turf and timber Roman fort was established in the early AD 70s and limited excavations close to the castle have located parts of the south and west defences incuding a waterlogged but well-preserved timber gateway. Futher excavation found that the fort's defences were moved further south in the second century and this may imply an enlargement of the fort area. In the third century the fort appears to have been enlarged again, limited excavation in Abbey Street and Castle Street found evidence for the defences of a stone fort south of the earlier defences. The fort was in use until the AD 330s. (30)

A number of important excavations were undertaken in the fort between 1998 and 2001. Carlisle's City Council's Gateway (Millennium) Project greatly enhanced the understanding of the origins and development of the fort. Excavations were focused in the south part of the fort, including the probable praetentura and a small area of the latera praetorii.
