History
Turret 41A is a Roman fortified structure on Hadrian’s Wall in the United Kingdom, near Haltwhistle. A turret was a small defensive building incorporated into the Roman frontier barrier across northern England. Turret 41A formed one of two such structures associated with Milecastle 41, a fortified enclosure placed at intervals along the Wall, and was probably manned by part of the milecastle’s garrison.
The turret stood at Caw Gap, about one-third of a Roman mile west of Milecastle 41. Exploratory excavation located it in 1912. During the later Roman period, the structure was deliberately demolished, and Hadrian’s Wall was rebuilt across its site. The surviving masonry was consolidated in 1972–73 and remains preserved at approximately 20 centimetres high.
