Painting by Rachel McKenna of Acres’ Folly before works

Garden folly built 1814, rectangular tower of 3 stogeys with rendered walls. Acres’ Folly is an unusual tower-like structure, which rises to some 9m in height from a ground plan measuring approximately 4m x 6m. Internally is contains a vaulted undercroft, while the upper rooms were originally divided by a partition in a proportion of one third to two thirds. Within the smaller space a timber staircase rose to what appears to have been a roof terrace, while the larger space provided basic, limited accommodation heated by an open fireplace in the gable end.

The purpose of the structure is not clear. It may have been constructed to serve as a watchtower, but is more likely to be a simple pleasure building combining summerhouse and prospect tower, to serve the nearby Acres’ Hall built by the prosperous Thomas Acres in 1786. Local tradition suggests that Acres’ Folly was built in 1812 to commemorate the victory of the Duke of Wellington over Napoleon during the Peninsular War.

Described by William Garner as being ‘erected in 1814 to celebrate the successful outcome of
