 Some of the 'outpost-forts' north of the Wall, and others such as Watercrook, seem not to have been maintained after 367, but Count Theodosius, or maybe local 'chieftains', did a fair amount of re-building and recovery work elsewhere.There is evidence of a narrowing of the gateway at Birdoswald, and structural changes at Bowness-on-Solway and Ravenglass, for example.There may also have been new fortlets at Wreay Hall and Barrock Fell, and possibly at Cummersdale, all south of Carlisle.
