More information : At NY 190 608, some 7m forward of Roman tower 2b, a single ditch was revealed on aerial photographs in 1975; subsequent excavations showed a ditch, 1.1m across and 0.4m deep, which had undergone three modifications. This it is suggested, is a part of a linear defence extending westwards from Hadrian's Wall at Bowness (1a). According to Austen (1b), further excavation by Jones in 1993, as yet unpublished, revealed two parallel ditches with evidence of a palisade trench between them. There is no trace on the ground. (1)
A narrow ditch was seen as a cropmark on air photographs. It extends either side of a tower (see NY16SE 9), but appears to be of a different phase. One section of the ditch has an unusual 'zig-zag'. It may be part of the frontier defence system, but appears to pre-date the stone phase of the tower. The ditch has been interpreted as a trackway. The interpretation of other linear features in the vicinity is uncertain. (2-3)
