Mausoleum And St Mary's Well, Duff House

The mausoleum at Duff House, built in 1790, is a rectangular Gothick structure that includes a re-sited late 17th century tomb. It is a single-storey building over a burial vault, featuring long three-bay elevations on the north and south sides, with two-bay return gables. The exterior is constructed of sneck harled rubble with tooled and polished ashlar dressings and margins. Engaged cluster columns define all bays and corners, and a pointed-headed doorway is located at the center of the north elevation, accessed by a short flight of steps. The entrance is adorned with a fine cast and wrought-iron gate that showcases intricate designs of foliage, anthemion, rosettes, an Earl's coronet, and the monogram JF. Flanking the entrance are windows, with three additional windows on the long south elevation and two in each return gable. All windows are unglazed and screened with heavy moulded ashlar astragals, each rectangular void filled with a cusped fillet, and the upper lights feature intersecting tracery.

A deep quatrefoil detailed Coade stone frieze runs below the eaves, and two wallhead Coade stone crocketted pinnacles remain from an original ten. The roof is piended and covered with slate.

Inside, the mausoleum has a simple and elegant plaster-walled interior, with each window framed by moulded ashlar jambs that have blocked imposts and depressed ogee lintels. Similar jambs mark the locations of marble mural memorials.

The tomb, which has been resited against the center of the south elevation, features a round-headed mural tomb with a recumbent figure. The table tomb is decorated with panels that include crossbones interspersed with ears of corn, symbols of mortality and rebirth, text, memento mori, and a saltire. The text from 1790 is placed over an earlier late 17th century Latin text.
