Wall Mile 72

Wall Mile 72 [HB 355–6]

Our journey takes us on, through the village of Burgh – crossing to the south of the Vallum as we go – and out into the countryside on the other side, still following the road.

Make the most of the gently undulating fields around us for we, like the Wall, are soon to leave the boulder clay that has defined the landscape around us since the central sector and the Whin Sill. The Wall has been over to our right, accompanied now by the Vallum. As we come to Dykesfield, the land drops and we approach Burgh Marsh. To the north of us, Milecastle 73 is likewise contemplating the marsh ahead.

The position of Milecastle 73 has been tested through geophysical survey and located on the ground sloping up from Burgh Marsh near Watch Hill, where Horsley thought there was ‘a castellum, for at this place they have dug up a larger quantity of stones than the bare thickness of the Wall could well have afforded’.
