Ardenne Abbey, or "l'Abbaye d'Ardenne", is the site of a Premonstratensian monastery in Saint-Germain-la-Blanche-Herbe, near Caen, France, containing a chapel built in 1121 and other medieval buildings.
The Abbey was used as an observation post by the Germans in the Battle of Normandy, and was heavily damaged by Allied forces. As a result, much of the Abbey visible today has been rebuilt or restored. The Abbey is most notorious for being the site of a massacre of Canadian prisoners of war during World War II.
