Entrance gateway to Thomas Firth and Sons Siemens Department

The entrance gateway to the former steelworks of Thomas Firth and Sons Siemens Department dates from around 1900. It is constructed of rusticated ashlar and features a plinth with flat coping. The gateway includes a carriage arch with a segmental head and multiple keystones, along with a doorway below. On either side of the arch, there are recessed panels with keystone lintels, and above these are windows. All openings are now filled with 20th-century railings. Below the coping, there is an inscription that reads "Thos Firth & Sons Ltd Siemens Dept." This gateway served as the entrance to the Norfolk Melting Shop, which was part of the renowned company. The name reflects the Siemens open-hearth process, which had become the standard method for producing steel in bulk by 1900. The large-scale steel industry in Sheffield began relocating to this area from the mid-19th century onwards.
