#Alongthewallin80days - Day 7
Although there are no visible remains above ground, Milecastle 73 is thought to have some of the best preserved sub-surface remains on what was the western end of the frontier. Milecastle 73 is known as Dykesfield. It is situated about a mile west of the village of Burgh by Sands. Milecastle 73 was located and partially excavated in 1948, it measured 19.2 metres north-south by 18.7 metres east-west internally, its stone walls were 2 metres thick. However when the Milecastle was located again and excavated in a geophysical survey, it measured 24.75 metres north-south and 26 metres east-west externally.The survey identified a possible road at the milecastle along with two probable enclosures that flanked the east and west walls of the milecastle. There were also indications of possible timber buildings outside the milecastle.
