 Gothic windows still adorn the southern wall, believed to have been inspired by those at Kilwinning Abbey (and are proof that much of the castle was built at various points in history).In 1852 Paterson noted arrow-slits and cable mouldings of pre-14th century date.An old bridge, now used for pedestrians only, is situated next to the ruin (NS 2688 4288), but the castle itself is fenced off to protect both the public from falling stone and the castle from unwanted attention.
