Arbeia is the site of a large Roman fort in South Shields, South Tyneside, which has been partially reconstructed (viz the gatehouse and the commandant's house). It was first excavated in the 1870s. It is now run by Tyne & Wear Museums.
"Arbeia" means "fort of the Arab troops", referring to the fact that part of its garrison at one time was a squadron of Syrian boatmen from the Tigris. We also know that a squadron of Spanish cavalry, the First Asturian, was stationed there. It was common for forts to be manned by units originally from elsewhere in the empire, though often enough these would assimilate and end up by recruiting locally.
Two monuments at Arbeia testify to the cosmopolitan nature of its shifting population. One commemorates Regina, a British woman of the Kentish Cattivellauni tribe, who was first the slave, then the freedwoman and wife of Barates, a Syrian merchant who evidently missed her greatly when she died at the age of 30. (Barates himself is buried at the nearby fort of Corbridge). The second commemorates Victor, another former slave freed by Numerianus of the First Asturian cavalry, who also arranged his funeral ("plantissime": with all devotion) when Victor died at the age of 20. The stone records that Victor was "of the Moorish nation".
