Coronation Street refused listed status Listed status is given to buildings of special architectural and historic interest and buildings more than 30 years old are usually eligible. The childhood homes of Lennon and McCartney are Grade II listed status because of their significance in popular culture for being where the duo wrote many of The Beatles' songs. In a statement refusing to include the current Coronation Street in its portfolio of properties, English Heritage said the set was "certainly unusual." They wrote: "The criteria against which we must assess the architectural significance of buildings - or in this case, a television set - is extremely strict. The oldest buildings are just less than 30 years old - and most do not have interiors and therefore exist as facades, most of which 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. Other listed buildings in the UK are the Grade I Blackpool Tower, Palace of Westminster and Albert Dock in Liverpool. The country has 19,717 scheduled ancient monuments, 1,601 historic parks and gardens, 43, registered historic battlefields, 46 designated wrecks, 9,080 conservation areas and 17 UNESCO World Heritage Sites. An ITV spokesperson said: "ITV continues to consider the future use of the Coronation Street set ahead of our planned move to MediaCity."
