Virosidum was a Roman fort and settlement situated near to the modern town of Bainbridge, North Yorkshire, England.

[2] In William Camden's 1586 Britannia the fort is referred to under the name Bracchium and this name persisted in early editions of the Ordnance Survey maps.

[7] The larger inscription records the reconstruction of four barrack blocks at the fort in AD 205 by the Prefect Lucius Vinicius Pius during the governorship of Gaius Valerius Pudens.

Isotope analysis of the strontium and oxygen values of their teeth found that the woman was probably local to the Yorkshire region, but that the other skeleton was from a western coastal part of Britain or continental Europe.

These burials may be consistent with structural changes to the western wall of the principia and the aedes (a temple) that suggest it was used as a church.
