Whitley Castle

Whitley Castle (Epiacum) is a large, unusually shaped Roman fort located north-west of Alston, Cumbria, England[1]. Built by the Roman Army early in the 2nd century AD, it was partly demolished and rebuilt around 200 AD[1]. Standing at approximately 300 metres (1,000 ft) above sea level in the Pennine hills, it is the highest stone-built Roman fort in Britain[1]. The fort appears to have been sited to protect lead mining in the area as well as to support the border defences of Hadrian's Wall[1].
