Portland Works is a former cutlery works in Highfield, Sheffield. Built in 1877 as a cutlery works by Robert F Mosley, is now a Grade II listed building with a wide variety of cultural uses. Three two- to three-storey ranges of brick-built workshops and a range of former offices and showrooms lie around a courtyard containing an octagonal chimney and some more recent structures. The central part of the rear range of workshops was reduced from three to two stories, following a fire. It was occupied for many years by R. F. Mosley, before being split into separate workshops. When first constructed, it was partially mechanised.
In 1914, through a collaboration between Harry Brearley, Ernest Stuart and R. F. Mosley at Portland Works, this became the first place in the world to manufacture stainless steel cutlery and this remains, to this day, one of the site's many activities.
