Description
Testwood Mill is the remains of a water mill, associated with a house, located at the south-west corner of the group. It dates from around 1840 and features walls of brickwork in English bond, a first-floor band, pointed arches, a second-floor drip mould, a brick-moulded cornice with a rounded stone bond at the top, and a thin coping stone on the parapet. The tower has a rectangular plan and consists of three stages. There is a ground floor doorway on the larger west side, along with doorways on the first floor of the south and west elevations, which are now filled or were originally panelled. The shallower top stage includes panelled roundels, with three on the west and two on the south. The south elevation displays the half gable of a demolished outshot, and the roof slope of this unit once covered the water wheel, which remains as three cast-iron frames that are partly buried. The original shaft leads through an existing opening in the tower, which still contains some ancillary machinery.
