A request for English Heritage to consider Castle Market for listing as a modern Brutalist building has caused worry to Sheffield City Council who say that if the building was listed, re-development plans around the site would be restricted. (July 2010).
Most of the market buildings in the Castlegate area date from the 1960s. They are made of concrete with walk-ways, stalls on several levels and an office block above the market.
However, if the 1960s building was listed, it would restrict access to the ruins of the 16th Century Sheffield Castle which is underneath the market. The ruins shown here are probably the castle tower where the Rivers Sheaf and Don meet.
Three sections of the castle's accessible remains were Grade II listed in June 1973. They can be viewed by appointment with Sheffield Markets. The lump of stone on the left has been cleaned by archaeologists. Faint markings can just be seen on its front.
Sheffield Castle ruins are in a small and unassuming room at the back of the market building. There are lots more remains underneath the building, which will only be able to be seen if the market is demolished.
The plaque outside the Castle ruins states that Mary, Queen of Scots spent some of her 19-year Sheffield imprisonment in the Castle here. Mary was also locked up in Manor Lodge which is just off City Road on the Manor estate.
Markets have been held in the Castlegate area for 700 years. The current Castle Market building opened in 1959 to re-house traders moving from the Norfolk Market Hall.
The fish and vegetable stalls in the 1930s part of Castle Market are the most popular area.
Sheffield City Council plans to demolish Castle Market and redevelop the Castlegate area, creating parkland around the Castle's remains down to the River Don. Traders will be moved to a new purpose-built market hall on The Moor.
Les Sturch looks after regeneration for the Council. He told BBC Radio Sheffield that Castle Market consists of "not very attractive, worn-out, not fit-for-purpose market buildings."
Planning permission has now been agreed for the new market hall on the Moor. The site is being prepared... (July 2010).
Some of the traders have been at Castle Market for many years and are not happy about a move to the Moor.
Castle Market has lots of cafés and other food outlets. There's even an American-style soda bar.
The concrete lift shaft and staircase on the market roof is typical of 1960s Brutalist architecture. John Rogers from Sheffield Markets thinks it was the first time this technique - concrete dropped on to a metal rod - was used to erect a staircase.
Castle Market was rejected as a candidate for English Heritage listing in 1995. The Council say they'll do everything possible to prevent it from being listed: "The land it stands on holds the key to regeneration for that part of the city."

Richard Webb emailed BBC Sheffield: "It's an eyesore which should be demolished as soon as possible so we can see the real heritage of Sheffield Castle beneath. The area is in desperate need of redevelopment - it's a disgrace to the city."
Although the 1930s fruit and meat market on the ground floors are still bustling, the walkways above - known as The Gallery - have many empty shops.
Much of The Gallery hasn't been changed since the 1960s, including these decorative ceramic tiles by the lifts and toilets.
The request for English Heritage to consider Castle Market for listing as a modern Brutalist building came from the public.
The Council's objections to the listing say that the proposals are "misconceived, inappropriate and detrimental to the protection of Sheffield's heritage, and that of the country as a whole."
Poppy in Sheffield emailed us to say: "I work in offices above the markets. The building is a crumbling mess and definitely not fit-for-purpose. We were gob-smacked that anyone would think these hideous buildings should be listed."
English Heritage will consult both sides before putting forward its report on listing status to the Secretary of State for Culture, Media & Sport.
