A major revamp of The Beacon museum in Whitehaven will go ahead after confirmation of a £1.3million funding package.
The museum will receive more than £900,000 from the Coastal Communities Fund.
The remaining £400,000 was awarded by the Copeland Community Fund last year.
The new design will include a conference and learning centre, and work is due to begin this year.
Bids are now open for this year's Coastal Communities Fund, with £4 million being provided for projects in Scotland.
The fund was created to encourage economic development and to provide sustainable growth and jobs.
Last year several projects on the Berwickshire Coast benefitted, including the Eyemouth Harbour Trust and the Eyemouth Museum Trust.
