The grassy earthworks of the Roman fort of Magna at Carvoran, where two Roman roads, the Maiden Way and the Stanegate, met just behind Hadrian's Wall. It has never been properly excavated. The Roman Army Museum stands beside it, and in summer volunteers give tours of the site. The pin is on the museum.

Although no proper excavations have been carried out at Magna, it has yielded many stone inscriptions – more than any other Wall fort.
