Castle Market
Castle Market is an indoor market in Sheffield, England. It lies in the north east of the present city centre, by the River Don, and is built on top of the remains of Sheffield Castle, which can still be seen via guided tours. The oldest part of the building is the Fish and Vegetable Market, constructed in the inter-war period. The remainder of the building was constructed by J. L. Womersley and Andrew Darbyshire between 1960 and 1965. It has two main floors, both including small shops and stalls, and each accessible from street level. Other stores face on to the surrounding streets, while a gallery found a storey above the main part of the market contains several more shops, and access to an office building surmounting the structure. The gallery is linked by bridges across Exchange Street to further above-ground shopping areas.

The whole Castle markets area has been the subject of redevelopment proposals since the 1980s, with part of the adjacent area being redeveloped with a hotel, multi-story car park and several new office blocks in a development known as "The Square" by Carillion. The original scheme to replace the markets fell victim to the 1990s recession. A new markets building is due to start construct as part of The Moor (Sheffield) scheme, which is part a partnership between the council and private developers. The multi-storey car park for the scheme has been built on Eyre Street. Part of the council's current plans is to demolish the existing complex and open up a pedestrian route from the city centre to the Victoria Docks area and the new Riverside Quarter, now that the ring road has been diverted.
