A pair of navigation beacons on the Caithness coast located a quarter-mile (0.4 km) south of Berriedale, the Duke's Candlesticks are traditionally associated with the Duke of Portland, the owner of the Langwell Estate on which they stand, although are thought to date from the early 19th century which would pre-date the Duke of Portland's ownership by some years. Their purpose was undoubtedly to guide fishing boats into Berriedale harbour.
One is a square tower, with blind windows, while the other is a round tower featuring a crenellated parapet. Given their similarity to chess-pieces, the pair are occasionally referred to as the Chess Bishop Folly and Chess Castle Folly respectively.
