A half-mile west of Pierowall stands this sturdy ruined tower house, built in the 16th century by Gilbert Balfour, aide to Mary, Queen of Scots. The castle is super-atmospheric and bristles with shot holes, part of the defences of the deceitful Balfour, who plotted to murder Cardinal Beaton and, after being exiled, the king of Sweden. Like a pantomime villain, he met a sticky end.
At the nearby Links of Noltland, archaeological investigation is regularly unearthing interesting neolithic finds. Most intriguing has been a chamber built over a spring, which was possibly used as a sauna.
