In the past Ardchattan has been co-joined with its neighbouring parish of Muckairn, on the other side of Loch Etive.
Its most famous landmark is Ardchattan Priory, founded as a Valliscaulian priory around the year 1230.
After the second world war the then owner Lieutenant-Colonel Robert (Bobby) Modan Thorne Campbell-Preston[4] married the hospital administrator and widow Angela Murray in 1950. Their daughter, Sarah, was born in 1951.[5]
The priory's ruins and surrounding gardens are now open to the public.
