Byland Abbey is a ruined abbey and a small village in the Ryedale district of North Yorkshire, England, in the North York Moors National Park. It was founded as a Savigniac abbey in January 1135 and was absorbed by the Cistercian order in 1147. It was not an easy start for the community who had had to move five times before settling at New Byland, near Coxwold in 1177.
Its early history was marked by disputes with no fewer than four other religious establishments: (Furness Abbey, Calder Abbey, Rievaulx Abbey and Newburgh Priory). However, once it had overcome this bad start, it was described in the late 14th century as "one of the three shining lights of the north". In October 1322, King Edward II was at Byland Abbey when the Battle of Old Byland took place. The marauding Scots caught Edward so unaware, that he fled to York leaving many precious items behind.
The site is now maintained by English Heritage and is scheduled as an ancient monument by Historic England.
