Statement of Interest

Bonnington Farm, which was originally the home farm of the Bonnington estate, is fine example of an 18th and early 19th century farm with a rare horse mill.

The farm forms a picturesque group round the court and is unusual for the gothick windows in the S gables of two of the buildings. Horse mills were a common feature of early Improvement Period steadings, their purpose being to operate the threshing machinery. In the early 20th century they were superseded by petrol or diesel operated machines and many horsemill buildings have since fallen into a state of disrepair or have been demolished. This horse mill is a good example in good condition and is also larger than usual.

Bonnington estate passed to Admiral Sir John Lockhart-Ross through his marriage with Lady Ross Baillie in 1757. Admiral Sir John was known to have been a notable estate improver, particularly at another of his estates, Balnagowan, which he inherited in 1754, and he is credited with the construction of Bonnington House. It is likely that he also developed the farm, in particular the farmhouse, the stable and the bothy. Sir John died in 1790, though the estate did not pass to his son immediately as Lady Ross Baillie is recorded as the owner on Forrest's map of 1816. She died in 1817 and, from that time her son, Sir Charles Ross-Lockhart his wife Lady Mary took a keen interest in the development of the estate and implemented many improvements during the period of their tenure. This included the development of paths, rides, view points and buildings and well as planting. The threshing barn and horsemill may date from this period.

The farm appears on both Johnston maps, the first dated 1780 and the other now thought to be late 18th century. The farm is clearly marked on Forrest's map of 1816. However the position of the buildings is hard to marry with map evidence and indeed evidence from the stonework of the buildings indicates various phases of building work and subsequent alterations.
