NG20NE 111 2750 0549

NG 2750 0549 A standing building survey was undertaken at the Bothy, Canna harbour, in advance of repair works. All extant features were recorded, and a photographic and graphic record was made. The Bothy represents the remains of an originally larger 18th-century mansion, superseded by the 19th-century Canna House. Although much reduced from its original three storeys, traces of the primary build and features survived.

NG 2750 0548 A historic building survey (DES 1997, 45) and an initial excavation (DES 1998, 60) proved the need for further investigation of the Bothy - part of the 18th-century laird's house on Canna known as Coroghon House (NG20NE 111/44) - before redevelopment of part of the building.

The excavation trench opened in 1998 was re-established and extended, with the following results. Coroghon House, built in the 1780s, had a central section which was originally 8.5m wide and 11.5m long. Subsequently, a W range was added. Its floor was a cobbled surface, c 1.5m wide against the old W gable, forming an edge to a beaten earth surface across the remainder of the area excavated. At a later date this floor was covered with sand and replaced with another, consisting of a cobbled surface abutting the interior walls of the range, forming a 'frame' to the main part of the floor area which was paved. It was after this floor was laid that the walls of the W range were rendered. There was evidence of another cobbled surface to the rear of the W range and abutting the NW corner of the main part of Coroghon House.

Much of Coroghon House was demolished when it was replaced by Canna House in the 1860s. Garden landscaping for Canna House used the c 2m high remains of the back wall of the central part of Coroghon House as a revetting wall. The Bothy, 6m wide and 11.5m long, was constructed out of the shell of the central part of Coroghon House, using the front wall and shortened gable walls, with a new build for the rear, N elevation.
