Barr Castle

Barr Castle is the ruin of a medieval tower house perched on a low ridge south of the village of Lochwinnoch in Renfrewshire, Scotland. Tower houses of this type were the fortified residences of minor Scottish landed families from the 14th to 16th centuries — more compact than full castles but unmistakable markers of local authority. The site is designated a Scheduled Ancient Monument, giving it legal protection against development or alteration. Visitors who make the short climb to the hilltop find an unmanicured, quietly atmospheric ruin with open views over the surrounding Renfrewshire countryside, with no visitor infrastructure to speak of — just weathered stonework and silence.
