The excavated remains of the Roman tower are visible on air photographs and were mapped by Historic England as part of the English Heritage Trust's 'Hadrian's Wall: Birdoswald Sector Survey'. The full perimeter of the tower foundations are visible, with an entrance at the south-west corner. It is clear on both aerial photographs and on the ground that Hadrian's Wall (1449984) abuts the tower, suggesting the tower to be earlier.
