Cinema's golden age reaches the final reel

They brought glamour into simple lives, but Britain's Art Deco picture palaces are being pulled down by developers with grand ideas

The bulldozers were hard at work last week in Lancaster, wreaking destruction on the 1936 Regal cinema in King Street. It was a classic example of Art Deco cinema design, but today all that is left of it is rubble.

More than 20 of Britain's 1930s cinemas could face a similar fate, as developers seek to strip out their interiors or raze them to the ground.

The ornate 1934 front of the Doncaster Odeon was turned to dust last month, to make way for a leisure complex, and the Newcastle Odeon – a 1931 former Paramount cinema – is now facing demolition after the Department for Culture, Media and Sport rejected a listing application.

Even the UK capital of cinema, Leicester Square in the heart of London, is not immune. The historic Odeon West End, which has dominated the corner of the square for more than 80 years, is facing a redesign that will relegate screens to the basement, to allow a hotel, flats and a restaurant to be built on upper storeys.

David Trevor-Jones, chairman of the Cinema Theatre Association, which campaigns to save the buildings, said: "We're losing swathes of and it's a tragedy. We live in a world of corporations and cheap architecture, but these buildings take you to another place. They're all about grandeur and supreme fantasy."

The association claims that the architectural significance of cinemas is overlooked because they are considered lowbrow. "I think cinemas are still undervalued; no town would willingly lose its Victorian theatre, but the same isn't the case for iconic cinema buildings," said Mr Trevor-Jones. "They're part of our social and cultural history, but they have no protection."

Many of the 22 buildings now at risk have not been functioning cinemas for years, but have been protected in their original state by accommodating bingo halls. Elain Harwood, a senior architectural investigator at English Heritage, says the demise of bingo has sounded the death knell for some of Britain's oldest cinema buildings.

"The bingo halls were the great saviour of old cinemas," she explained. "When a lot of the old cinema and theatre buildings closed in the late Fifties and early Sixties they were turned into bingo halls and therefore preserved. In the last two years, since the smoking ban, bingo has been in freefall and loads of cinema buildings are now out of use. Even those that are Grade II-star listed are under threat, because they have been empty for so long."

There are just under 200 listed cinemas in England, of which 26 have a Grade II listing that protects the whole building. This does not stop the threat of developers, however, if a building remains disused for some time. The only cinema with Grade I protection is the former Granada in Tooting, south London.
