Milecastle 48
Milecastle 48 is located to the south west of the village of Gilsland, and is one of the best preserved milecastles on the entire length of Hadrian’s Wall.
Milecastles were built at every Roman mile along the wall, to enable control of people crossing from one side of the wall to the other. Between each milecastle were two turrets, equidistant between the milecastles, which were designed for temporary occupation by soldiers patrolling the wall. There are good examples nearby – Banks Turrets 51B and 52A.
