The spire of Big Ben will begin to be revealed after months of work on the iconic spire at parliament left the tower completely obscured by scaffolding.

The 98m tower, which has become a national symbol since its completion in 1856, has been mostly hidden from view as efforts to restore the historic building progress.

Now the newly restored spire and rooftop of the Grade 1 UNESCO world heritage site will begin to be uncovered over the next five weeks, with the first results of the building work becoming visible on 7 October.

Adam Watrobski, principal architect on the project, said: “The first section of scaffolding coming down is a key moment in the project.

“It means that we are getting nearer the end and that people can again enjoy this symbol of our nation and of democracy.

“A lot of hard work and ingenuity has brought us to this point and while there is much work still to be done, it is worth pausing to appreciate how far we have come.”

The name Big Ben was first given to the bell housed within the tower – however it has since become synonymous with the spire that flanks Westminster palace, which was originally called the Elizabeth Tower, as well as its clock faces.

Its gradual unveiling marks the progress of the project to renovate the landmark, which began in 2017 and is due to be completed in 2021.

Charlotte Claughton, senior project leader, added: “Removing the scaffolding in stages is part of our commitment to make sure as much as possible of this iconic landmark is visible to the public.

“We share the world’s love of the tower and the clock and I know the whole team feel so privileged to be part of this project.

“And now we get to show everyone a bit more of what we have been working on.”

The bell itself was silenced due to restoration in August 2017, returning again briefly in November that year when it chimed out for Armistice Day.

It has since only been used to mark special occasions, and will return to full use in 2021.
