The date of origin of this polygon relates to mid 19th century buildings fronting on to Saville Street, including the Don Saw Mills (currently awaiting restoration or redevelopment (2005)) and the 'Old Hole in the Wall' public house (similarly derelict and the only surviving evidence of a mid 19th century brewery that stood on the site of Saville House). Mid 19th century character is also provided by the imposing nearby presence of the massive stone arches of Victoria Station to the south. On the southern bank of the Don are the vacant site of a railway engineering works and the Britannia Steel works (both on Sussex Street). The Britannia Steel Works survives and dates to the early 20th century. It contains one of the few remaining crucible stacks. The SMR records this area as within the historic boundary of Sheffield Park.
