Turret 54A (Garthside) (grid reference NY54546439) was excavated in 1933.[3] The excavations revealed two stone turrets. The earlier turret had stood upon bad ground and its front wall had collapsed, after which the second had been built upon the firmer crest of the hill.[3] The pottery found at both turrets suggested they were built in the early 2nd century and occupation probably ceased about 180 AD.[3] There are no surface remains visible.[3]
Hadrian's Wall in the vicinity of Turret 54A survives as a substantial turf covered bank at the base of a hedge.[2]
