Barr Castle
Barr Castle is a late medieval Scottish tower house standing on a low ridge south of the village of Lochwinnoch, Renfrewshire. The rectangular stone tower survives as a ruin today but was once a multi-storey residence with ancillary courtyard buildings and defensive battlements.

As it stood in 1699
The shape it held in its prime.
A simple rectangular stone tower roughly 7.8m by 10.7m on plan, rising to corbelling for four angle turrets about 12m high; walls of roughly-coursed, square-faced masonry with dressed corner quoins. The south side retains a chimney stack and part of the gable; the west face has a pedimented entrance carved with initials. Window openings puncture all sides. The tower stands on a low grassy ridge with scattered mature trees and low-lying water nearby, and formerly had a courtyard of subsidiary buildings attached to the south.
Its story
The story of Barr Castle.
Barr Castle was built by the Glen family — a late-medieval tower house on a low ridge south of the village of Lochwinnoch in Renfrewshire, a plain rectangle of roughly-coursed masonry standing some twelve metres to the corbelling of its four vanished angle turrets. Unusually for a Scottish castle, its first-floor hall had a flat, low ceiling instead of the usual loftily arched form.
On the death of Alexander Glen in April 1629 the castle passed to the Hamiltons of Ferguslie; the pediment above the main entrance is inscribed with the initials of Margaret Hamilton and John Wallace. The tower was converted into a larger residence, probably in the late 17th century, and the Hamiltons retained it until the late 18th century, when they sold and abandoned it for a new mansion — John Hamilton, Alexander's grandson, selling the estate to the MacDowall family.
As of 2011 Barr Castle is owned by Fergus MacDowall of Garthland, Chief of the Clan MacDowall, and because of his status the ruin is regarded as the clan seat — though the MacDowall family have little historical connection with the castle beyond ownership, since the 18th century, of the land on which it was built.
