Swarthy Hill Roman Mile Fortlet 21 was a small Roman military installation, part of a system of frontier defenses along the Stanegate road, likely dating to the 2nd century AD. It is associated with the Roman expansion into northern Britain and provides evidence of the infrastructure supporting the construction and maintenance of Hadrian's Wall.
