Two of Scotland's most popular tourist attractions are set to close indefinitely.

The Winter Gardens in Glasgow Green will shut at the end of the year over safety concerns, while the People's Palace is also facing closure.

Structural engineers have estimated that it will cost Glasgow City Council up to £7.5m to bring the Victorian glasshouse up to an acceptable level of safety.

Primary safety issues stem from the Winter Gardens, which date back to 1898, but as the fire escape from the People's Palace requires access to the glasshouse, it will also have to close.

Council bosses are said to be working on options to allow the People's Palace, which houses historic artefacts, paintings, prints and photographs, film and interactive computer displays, to remain open independently of the Winter Gardens - which is operated by arm's length external organisation Glasgow Life.

A Glasgow City Council spokesman said: "The Winter Gardens will unfortunately have to close at the end of this year, due to concerns about the safety of the structure beyond that point.

"We are currently working on options to allow the People's Palace to remain open independently of the gardens.

"At this stage, we do not know how long the Winter Gardens will remain closed. However, we estimate that investment of between £5m and £7.5m will be required to make it safe for public use.

"With that in mind, we are currently examining how we use both the People's Palace and Winter Gardens.

"The aim is to secure a sustainable, long-term future for an iconic building in one of the city's most-loved spaces.

"A full report of the plans will be submitted to elected members and the relevant committee in due course."

All bookings for the venue have been suspended, but those already scheduled to take place will be allowed to go ahead as planned.

There is not believed to be any safety risk to those using the venue in the run up to its closure.

David McDonald, the depute leader of Glasgow City Council, said: "Closure of the Winter Gardens is a devastating blow, but they are in need of massive investment.

"We are looking at all options to keep the People's Palace open during closure of the Winter Gardens and planning how to create a sustainable long-term future for both."

The Winter Gardens are known to host various events including corporate dinners, award ceremonies and weddings.

The venue is also used as a VIP area for guests at events taking place within the park, including the recent TRNSMT festivals.

Labour MSP Anas Sarwar tweeted that the closure of the "iconic building" will have a negative impact on tourism and the local community.

He added: "One way we can protect and invest in some of our most treasured facilities is by introducing a tourist tax."

Still Game actor Gavin Mitchell, who plays Robert 'Boabby the barman' Taylor in the hit show, is also disappointed.

He tweeted: "This is heartbreaking, one of Glasgow's most iconic and important visitor attractions to the local area."

Alison Thewliss, SNP MP for Glasgow Central, added: "Hoping a solution can be found - the People's Palace and Winter Gardens are too precious to lose."
