The most famous street in the north of England has failed to win listed status as an historic building because of its constant reinvention to suit the changing demands of TV drama.
The redbrick terrace of Coronation Street, which is threatened by redevelopment as the city's media move from central Manchester to Salford Quays, lost out after a detailed analysis by English Heritage.
For all its lore and grip on the national imagination – "Corrie" is comfortably the world's longest-running, and typically the UK's most-watched TV soap – the actual bricks and mortar are comparative newcomers. Although increasingly "real", with the fibreglass chimneys being replaced by brick to meet the demands of high-definition TV, they only date back to 1982 and have had many additions since.
English Heritage said it failed the listing system's "extremely strict" criteria on age, albeit only by months, but other problems with supposed historic and architectural value were rife.
The ruling says: "Most of the houses do not have interiors and therefore exist as facades, and most of those have been altered. The set as it stands today is an active reminder of the long-running television programme, rather than a survival of an earlier era of television productions."
The full-size street was opened by the Queen, an indication of the show's status rather than the quality of the set. Its two predecessors were built smaller than life-size to fit into Granada TV's production space, obliging actors to walk more slowly than normal. The first set was indoors; the second outside and unpopular with staff because it was built at an angle which caught the wind.
The set has attracted some support from conservationists and Mancunian loyalists who believe the fictional city of Weatherfield, first introduced to viewers in 1960, is Manchester and not its neighbour and rival, Salford, the home of Media City where ITV Granada is building a new set. A number of housing and tourism groups are thought to have approached the company, which is expected to move out next year.
ITV Granada said in a statement: "We continue to consider the future of the Coronation Street set ahead of our planned move to Media City".
Nick Bridgland, of English Heritage, said: "There is no question that Coronation Street is a television institution and holds a huge place in many people's hearts. While listing is not appropriate for the set, a better solution could be for a local group or organisation with an interest to care for it and allow fans from all over the world to visit and enjoy it."
