Lunt Roman Fort

The Lunt Roman Fort is the archaeological site of a Roman fort, of unknown name, in the Roman province of Britannia. It is open to the public and located in the village of Baginton on the south eastern outskirts of Coventry. The fort has now been fully excavated and partially reconstructed; the wooden gateway rebuild was led by archaeologist Margaret Rylatt, using the same tools and techniques that the military engineers of the Roman Army would have used. In 2001, Anglo Saxon artefacts dating to Sub-Roman Britain were discovered on the site.Four periods of occupation of the fort during periods of unrest in Roman Britain have been identified by excavation. The fort was built around AD 60 to act as a supply depot and headquarters for an unknown legion during the final campaign against Boudica.From AD 64 it was used, in the second phase, by a cohort which reduced the size of the fort, but from which the principia, praetorium, two granaries and six barrack blocks have been excavated. A number of buildings were demolished to construct a gyrus.[citation needed] Many horse fittings, possible stabling, an extensive metalworking area, granary and storage space suggests a cavalry unit was present at this time. This second phase lasted until AD 77/8.The third period of AD 77/78-79 included construction of a double ditch system, a twin-portalled gateway on the south and occupation outside the defences until the fort was decommissioned.After AD 260, perhaps during the rebel Gallic Empire, it was recommissioned as a temporary fort with ditches on a similar alignment but slightly larger than that of Period 2.Gyrus
The north, south and west sides followed the usual pattern for a Roman camp of straight ditches and ramparts. However, on the eastern side the defences bulge out around a circular structure with a diameter of 32 m (105 ft). The sand and gravel subsoil had been dug out to a depth of 600 to 900 mm (24 to 35 in) and the area surrounded with a timber stockade.This ring, the only known "gyrus" in the Roman Empire, may have been used for training horses. The gyrus was added to the fort during its second period of occupation and its construction caused significant disruption to the fort. Having the gyrus within the fort affects not just the wall which curves to accommodate the structure deviating from the Roman playing card shape pattern but also the layout of the fort which is significantly different from the standard layout. This makes the fort unique not just in Britain but also in the Roman Empire.
