Darwen Tower’s replacement dome will last 150 years, say engineers working on the project.

Apprentices at WEC Group, based in Junction Street, Darwen, will build a new dome to the same style as the one which blew off in strong winds in November.

And it will be free of charge as part of a class project.

The group has not released details of the material to be used, but says it will not be stainless steel.

Managing director Steve Hartley has made the gesture as a way of supporting the local community.

He said: “I think it will be a long time before the government can look at paying for this kind of project and I want to support the local community’s efforts.

“The dome will be in exactly the same style as the one it replaces because of planning issues.

"There is no date yet for completion.”

A helicopter belonging to Mr Hartley will be used to lift the dome back into place when ready.

Six other local companies had also offered their help in the project.

A public subscription fund organised by market trader Eileen Guy has so far raised £700 for the dome’s repair – money that will now be used to renovate the interior and exterior.

And the work will be co-ordinated by the newly-formed Friends of Darwen Tower group.

Coun Coun Stephen Potter, from the group, said: “It’s an iconic symbol of Darwen and it means a lot to the people to have it restored to its former glory.

“Hopefully, now that the friends group has been set up, we can attract funding and make access to the landmark easier.”

Anyone wishing to donate to the fund can now pay at any NatWest bank, quoting Darwen Tower Repair Fund.
