Associated Towers

Each milefortlet had two associated towers, similar in construction to the turrets built along Hadrian's Wall. These towers were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milefortlet, and would probably have been manned by part of the nearest Milefortlet's garrison. The towers associated with Milefortlet 4 are known as Tower 4A () and Tower 4B (). The position of Tower 4A is uncertain, although it thought to lie on the crest of a ridge with good views seaward. Tower 4B is located in a field west of Cardurnock. It was excavated by in 1977, which located three sides of the tower surviving as robber trenches: the western side having been completely eroded. The tower was interpreted as having had three phases: in the first two phases palisade structures were built, but in the third phase these were abandoned and a stone tower was built.
