Housesteads Roman Fort is the remains of an auxiliary fort on Hadrian's Wall, at Housesteads, Northumberland, England, south of Broomlee Lough. The fort was built in stone around AD 124, soon after the construction of the wall began in AD 122 when the area was part of the Roman province of Britannia. Its name has been variously given as Vercovicium, Borcovicus, Borcovicium, and Velurtion. The 18th-century farmhouse Housesteads gives the modern name. The site is owned by the National Trust and is in the care of English Heritage. Finds can be seen at the site, in the museum at Chesters, and in the Great North Museum: Hancock in Newcastle upon Tyne. History Hadrian's Wall was begun in AD 122. A fort was built in stone at the Housesteads Roman Fort site around AD 124 overlying the original Broad Wall foundation and Turret 36B, about two miles north east of an existing fort at Vindolanda. The fort was repaired and rebuilt several times, its northern defences being particularly prone to collapse. A substantial civil settlement (vicus) existed to the south, outside the fort, and some of the stone foundations can still be seen, including the so-called "Murder House", where two skeletons were found beneath an apparently newly-laid floor when excavated. In the 2nd century AD, the garrison consisted of an unknown double-sized auxiliary infantry cohort and a detachment of legionaries from Legio II Augusta. In the 3rd century, it comprised Cohors I Tungrorum, augmented by the numerus Hnaudifridi and the Cuneus Frisiorum, a Frisian cavalry unit, cuneus referring to a wedge formation. The Tungrians were still there in the 4th century, according to the Notitia Dignitatum. By 409 AD the Romans had withdrawn. Most other early forts straddle the Wall and therefore protrude into barbarian territory. It is also unusual for Britain in that it has no running water supply and is dependent upon rainwater collection (for which purpose there is a series of large stone-lined tanks around the periphery of the defences). It also has one of the best-preserved stone latrines in Roman Britain. The name of the fort has been given as Borcovicus, Borcovicium, and Velurtion. An inscription found at Housesteads with the letters VER, is believed to be short for Ver(covicianorum) – the letters ver being interchangeable with bor in later Latin. The name of the 18th-century farmhouse of Housesteads provides the modern name. The site is now
