Hadrian's Wall - Milecastle 39

There were lots of people out on the wall - here is Milescastle 39, north of Once Brewed, near Steel Rigg. We called in at Twice Brewed (pub) which has been completely refurbished and extended.

'A milecastle was a small fort (fortlet), a rectangular fortification built during the period of the Roman Empire. They were placed at intervals of approximately one Roman mile along several major frontiers, for example Hadrian's Wall in Great Britain (Britannia in the Roman period), hence the name.'
