Twelve people have been told to remain at the top of Blackpool Tower for their own safety after a fire broke out on the roof of its famous ballroom.
The fire service said the blaze was believed to be in the fourth floor of one of the buildings beneath the tower.
Blackpool Council said the tower was evacuated as a precaution at about 13:00 GMT.
The fire service said 12 people were being held in a “safe area” at the top of the tower as a precaution.
Kate Shane, general manager at the tower, confirmed the fire broke out on the roof of its ballroom, which is the annual venue for an episode of BBC One’s Strictly Come Dancing.
Smoke could be seen rising from the base of the attraction, but the BBC understands firefighters were still trying to identify the precise location of the fire.
Shaun Miller said his girlfriend Lynne Buckland had been stuck at the top of the tower since 11:20 GMT.
He added: “It was probably the safest place to be if something major had happened.”
Ms Buckland said people were being well treated.
“We are a bit fed up but at the end of the day we’ve got fantastic views and they are keeping us refreshed,” she added.
“Everyone has been fantastic and we had to make the most of it.”
Bank Hey Street has been closed while the incident is dealt with, Lancashire Police said.
There have been no reports of any injuries.
