Sara's Foundry, Town Mill

Sara's Foundry, also known as Town Mill, is an iron foundry and engineering works that dates from the 19th and 20th centuries, with an earlier core. The building features some coursed granite rubble but is primarily clad in corrugated sheet on a timber frame, with a damaged roof. The oldest part of the structure is the former corn mill, a small rectangular stone building located at the west corner, built into the bank below the goit, and has a small water wheel attached to its rear wall. The north side wall extends to the east and originally housed two larger water wheels, one measuring 16 feet in diameter and the other 32 feet, although the latter was dismantled due to storm damage by the time of the survey in 1988.

While the exterior of the building is less notable, the interior contains significant machinery and equipment, including reduction gearing for generators, a diesel engine, belt drives, timber cranes, a 40-foot lathe believed to have been made on site, large pillar drills, shaping machines, and rock-drills produced by the foundry, along with a substantial collection of associated tools. Although much of this equipment is rusted from disuse, it remains in a similar condition to when operations ceased around 20 years ago, and some pieces are thought to be rare survivors.

Historically, the original corn mill was known as Town's Mill, and the foundry is believed to have been established by the Sara brothers around 1850. The foundry forms a group with the associated dwelling, Foundry House.
