Glendevon Castle is a collection of conjoined structures dating from the 15th century.
It lies on a private road in a wooded area north of the A823 between Glendevon Village and Gleneagles.
The Historic Scotland description surmises that the structure was greatly reduced in size in 1766, as a date-stone bears this date.
[3] From 1966 to around 1987 the building held a "wayside hostelry" known as the Dungeon Bar in its vaulted basement.
[4][5] The bar was partly linked to a caravan park on the low-lying ground to its west.
