Occupied between the 1st and 5th centuries AD, it protected a key Roman road in the north of England.

The name Verterae, or Verteris,[1] is of Brittonic origin, and derived from the element werther, a plural form meaning either "ramparts" or "high places" (Middle Welsh gwarther).

Verterae was probably built by the Roman governor Gnaeus Julius Agricola between AD 79-80, as part of his campaign to conquer the north of Britain.

Old gazetteers claim this fort gave its name to the Maiden Way – the old Roman road from nearby Bravoniacum (Kirkby Thore) north to Magnae (Carvoran) on Hadrian's Wall.
