Airthrey Castle is a small Gothic Revival country house designed in 1791 by Robert Adam for Robert Haldane of Airthrey. It is one of Adam's last commissions — he died the following year — and the only one in central Scotland. The exterior is a compact, picturesque assemblage of round towers, battlements and pointed windows; the interior was reworked in the 19th century and the original Adam plan has been heavily altered.
The house and its surrounding parkland were bought by the new University of Stirling in the 1960s, and the castle now contains university offices. The grounds are open to the public and include the 17-acre Airthrey Loch, a number of mature specimen trees (including a 200-year-old yew and a tulip tree), and a small walled garden.
It sits at the eastern end of the university campus. There is no formal admission to the castle interior, but the exterior and grounds are worth a stop on a campus walk.
