This large and impressive ruin lies half a mile inland from Rosehearty. It was originally built by the Frasers of Philorth in 1424 but passed to the Forbes of Druminnor who extended it in the 1570's. The last resident of Pitsligo was Alexander Forbes, 4th Lord Pitsligo. He was a fervent Jacobite supporter who was forced into hiding when his lands were forfeited after Culloden. He evaded arrest by various legendary means for the rest of his life, dying in 1792 aged 84 and still a free man. In 1989 the castle was bought by Alexander Forbes' relative, Malcolm Forbes the American multi-millionaire publisher, who had renovations executed to secure the structure of the building prior to his death in February 1990.
