Yesterday the Theatre Trust highlighted 49 theatres across the UK it believes are "at real risk of being lost unless owners recognise they are responsible for community assets and work with trusts and local communities to secure their future".
The theatres in Scotland, some of which are already being cared for by trusts, private owners or other bodies wishing to preserve them, are the Britannia Panopticon and the Old Athenaeum in Glasgow, Leith Theatre in Edinburgh, the Odeon in Edinburgh and the Tivoli in Aberdeen.
The two theatres in Glasgow have differing histories. The Panopticon, in Argyle Street, which is the world's oldest surviving music hall, had around £1 million spent on a "facelift" in 2009 and still holds events, while the Athenaeum, now a high-end retail space, is no longer a working theatre and is unlikely to be utilised as one again.
Trusts are also attempting to redevelop the Leith Theatre in Edinburgh and the Tivoli in Aberdeen.
Mhora Samuel, director of The Theatres Trust, said: "There's good news that overall the number of buildings on our Theatre Buildings At Risk Register has come down from 56 last year to 49 this year.
"And we're pleased some have found the funds and support they so desperately needed, such as the Gaiety in Ayr. However, we've also lost some important venues and I'm very concerned about the future of the 17 theatres we've added to the register."
A spokesman for Glasgow City Council said: "Considerable work has been undertaken to ensure the structural integrity of the Panopticon and now the focus is on finding ways to bring it back into active use.
"The Old Athenaeum has been converted into a retail space with all the appropriate consents in place and is now awaiting to be let."
The Gaiety theatre in Ayr, which has been removed from the "at risk" register, has secured funding from the Scottish Government and South Ayrshire Council to enable it to undertake a programme of capital works, and plans to reopen later this year.
Theatres in Scotland also removed from the 2011 Register are the Ramshorn in Glasgow, now under the care of the University of Strathclyde, the Stockbridge Theatre in Edinburgh, which is likely to receive planning permission for change of use, and the Gateway in Edinburgh which has permission for demolition.
Founded in 1857 on the Trongate, the Britannia over the years the stage saw performances by stars of the stage such as Harry Lauder and, perhaps most famously, Stan Laurel in 1906.
The Friends of Britannia Panopticon and the Britannia Panopticon Music Hall Trust work to ensure the building's preservation and provide an events programme. The Theatre Trust report, however, says: "The building still requires significant investment to make it accessible and more useable."
The Old Athenaeum has stood on Buchanan Street for almost 120 years and was bought by businessman Ken Cairnduff in 2005 for around £3.5 million. He transformed it from a semi-derelict theatre into a 40,000 sq ft retail space suitable for shops.
