This impressive Augustinian priory, founded around 1169, is just a stone's throw from Hadrian's Wall. Its ruins tell stories of kings, wars, and pilgrims. King Edward I stayed here in 1306 during his final campaign against the Scots, and Robert the Bruce later attacked the monastery. The church ruins still stand tall, with a dramatic triple-arched structure. Built partly with stones from Hadrian's Wall, they include Roman inscriptions. Inside, you'll find the Lanercost Cross (1214) and the Lanercost Dossal, a work of art designed by William Morris.
A must-do when cycling Hadrian's cycleway; for a modest fee you are granted free passage to the whole of the priory grounds. The staff are well informed and friendly.
