nineteenth century and exported all over the world. Production ceased around 1912, but parts of the site remained in use until 1929. One of the Top Forge hammers was run as a demonstration in 1933 or 1934. In 1955, the dream of C. R. Andrews (the son of the second Thomas) was fulfilled, the forge being reopened as an industrial museum by Sheffield Trades Historical Society (now South Yorkshire Industrial History Society). From the mid-1960s the Honorary Curator of the forge for over 40 years was Ken Hawley, who was the driving force behind a team of volunteer workers who preserved and restored the forge into its present condition – work that was recognised when he was appointed MBE in 1998. Of particular interest is that the site only ever used waterwheels to power the machinery. All three waterwheels have been restored to working order. Its buildings are used to house a variety of industrial machinery, including a Marshall twin-cylinder steam engine. Heritage designations The whole of the site is a Scheduled Monument and the main forge is a Grade I listed building. Top Forge Cottage, and two other cottages south of the forge, are listed separately at Grade II.
