Inchaffray Abbey
United Kingdom
Inchaffray Abbey was situated by the village of Madderty, midway between Perth and Crieff in Strathearn, Scotland. The only traces now visible are an earth mound and some walls on rising ground which once (before drainage) formed an island where the abbey once stood (the surrounding marshes known for eels).
