Visitors to Inveraray Castle are often amazed by the brilliance of the extravagant decoration in the State Dining Room. The elaborate painting was completed in 1784 by two French painters Girard and Guinard, whose work only survives at Inveraray.

The painting is of a quality unparalleled in Britain at that time and it is little surprise to find that Girard was one of the principal decorative artists employed by the young Prince of Wales when decorating his grand London residence Carlton House.

Other features include a set of Beauvais tapestry upholstered 'fauteuils' (chairs with open arms) commissioned by the 5th Duke, delicate gilding by Dupasquier and two outstanding ormolu-mounted sideboards dating from the late 18th century.

The dining table, by Gillow of Lancaster dates from about 1800 and the Waterford chandelier, the largest of three, of which the smaller pair hang in the Tapestry Drawing Room, is circa 1830.
