Wall Mile 77

Hadrian's Wall survives as a buried feature throughout the whole of this section. Excavations by Haverfield in 1899 located the Wall between Burgh Marsh and Drumburgh fort. The Wall measured 2.95m wide and the wall ditch was 8.9m wide and lay 8m north of the wall. Excavations by Charlesworth in 1973 confirmed the course of the Wall north of Glasson. Geophysical survey has also located the line of the Wall or wall ditch to the north east of Glasson.

The exact location of milecastle 77 has not yet been confirmed. Excavations by Charlesworth in 1973 proved inconclusive in determining its position. On the basis of the usual spacing it is expected to be situated about 50m south of the junction of the Glasson road with the Bowness-Carlisle road.

The exact locations of turrets 76b, 77a and 77b have not yet been confirmed. On the basis of the usual spacing turret 76b is expected to be located about 90m south of where the dismantled railway crosses Hadrian's Wall east of Glasson and turret 77a approximately 140m south east of Lowtown House. Turret 77b is believed to be beneath Westfield House or its yard

The course of the Roman road known as the Military Way, which ran along the corridor between the Wall and vallum linking turrets, milecastles and forts, has not been confirmed in this section. It is expected to run parallel to the course of the Wall set back a few metres to the south.

The vallum survives as a feature visible on the ground throughout most of this section. At the eastern end of the monument the vallum ditch is utilised by a modern drainage ditch 5.7m wide and 2m deep. The course of the vallum between the watercourse 400m south east of Glasson and Burgh Marsh has not yet been confirmed and is therefore not included in the scheduling.

West of Glasson the line of the vallum ditch is visible as a faint shallow depression but at the west end of the monument it survives in the field immediately east of the access track to Glendale caravan park as a more obvious earthwork up to 0.8m in depth.

Hadrian's Wall survives throughout this section as a buried feature. There is no evidence for the ditch to the north of the Wall, and it is likely that in this section parallel to and close to the Solway shore the ditch was not [needeed].

Hadrian's Wall survives throughout this section as a buried feature. It is not known whether the ditch to the north of the Wall was provided here as the wall runs parallel to and close to the Solway shore in this section of the monument.

Hadrian's Wall survives throughout this section as a buried feature. West of milecastle 78 the Wall turns northwards to follow the Solway coast in contrast to the vallum which runs straight in this section. It is not certain whether the ditch to the north of the Wall was provided in this section, as a ditch would have been superfluous so close to the shore and liable to tidal flooding. There is no evidence for the ditch on its depicted line. The Wall in this sector was initially constructed in turf, which was replaced in the second half of the second century by the stone wall.

The course of the Roman road known as the Military Way, which ran along the corridor between the Wall and the vallum linking turrets, milecastles and forts, has not been confirmed in this section.

The course of the vallum is known in this section. The vallum ditch can be traced as a depression up to 0.8m deep. The vallum mounds are not visible in this section and have been reduced and levelled by ploughing. They survive as buried features.
