Banff and Macduff are twin burghs in Aberdeenshire, Scotland. Banff lies on the west bank, and Macduff on the east bank, of the mouth of the River Deveron. The towns have an aquarium, beaches, and are home to the Colleonard Sculpture Park. Also in the burghs is Duff House, designed by William Adam in 1730, and now part of the National Gallery of Scotland. Banff was formerly the county town of Banffshire.
