The Pavilion Theatre is the oldest venue in the Church Street Grade II-listed complex and part of the original 1878 build by Thomas Mitchell.
Whilst largely shut for 10 months, the site is currently back in action, opening as a mass vaccine centre for the roll-out of the national Covid vaccination effort.
The Pavilion has run as an entertainments hub and event space for more than 140 years, through performances to exhibitions and festivals, catering for audiences
of up to 900 people.
The Trust, the national advisory body for theatres up and down the land and which champions the importance and future of live performance through the protection of buildings, has released its 2021 ‘at risk’ register.
The resort’s North Pier Pavilion has also been included in the list as a venue considered as a valuable asset to its community.
But bosses for Blackpool Entertainment Company, which runs the Winter Gardens, said the venue remained an 'integral space' within the Winter Gardens.
A spokesperson said: "The Pavilion Theatre is an integral space at the venue, it supports existing events and continues to hold a diverse programme of content each year including the JORVIK exhibition that ran during the Autumn last year.
"As a venue we continue to work closely with Blackpool Council and key partners to ensure the continued use, protection and longevity of the venue."
In a statement, the trust said that, while the uncertainty owing to the pandemic has had a “devastating” impact on the UK theatre industry, “relatively few theatre operators have ceased trading and fortunately none of the buildings left empty look to be in imminent danger.”
Some 21 theatres have been unveiled on the register, highlighting venues that are in need of refurbishment but could be of greater value to communities if they are given more support.
Other county venues include the Victoria Pavilion/Winter Gardens in Morecambe and the Burnley Empire.
Bosses at the trust have said they hope to look to “constructive collaboration with all owners to secure a positive future for these important theatres”.
Director Jon Morgan added: “This past year has shown that communities value places where they can come together and that audiences miss live performances.
“While the theatre sector still has challenging days ahead, Theatres Trust believes that theatre will come back stronger than ever and that each building on the Theatres at Risk list has real potential to be a valuable asset to its community, to bring much needed footfall to its town centre and spark regeneration of its area as part of the recovery post-Covid.”
