The Cartouches. Two cartouches, in the west and east coves, have romanticised depictions of the ancestral Crichton properties, Sanquhar Castle and possibly Leifnorris.

The decorative plasterwork and cartouches in the Entrance hall were originally in white. However, in the late nineteenth century, the 3rd Marquess of Bute commissioned decorators to add colour and gilding. The Great Steward of Scotland's Dumfries House Trust chose to reduce the heavier elements of the gilding and return the Hall generally to stone and dark grey colours more in keeping with eighteenth-century design.
