Legio XX Valeria Victrix but no evidence was found for an occupation later than late Antoninus Pius period. Sherds from as many as fifty flagons were also found, along with more amphora sherds than would be expected. Five gaming pieces were found outside the North-West corner of the turret, possibly indicating the existence of a window in the west wall. Further objects of copper and iron, including an arrowhead, were found. The walls were constructed with mortar. The floor was constructed from clay containing mortar, and there were dumps of this substance found outside the walls. The internal south-west corner was marked off by boulders as a working area, with a hearth (renewed twice). A platform was later added against the south wall. A path led from the turret, with traces of a wall evident on its left. Location on Ordnance Survey 1:25 000 map: Monument records References Bibliography External links 25 Wall, Northumberland
