A derelict Art Deco cinema in Margate is to be brought back into use with the help of £1.8m of government funding.
The cash, to restore the cinema on the Dreamland site in Kent, has come from the Coastal Communities Fund.
Two other projects in West Sussex and Cumbria also received support.
In Littlehampton, £573,000 will be spent on revitalising the riverbank, and Whitehaven will see a £450,000 upgrade of part of the Rosehill Theatre to create a contemporary arts centre.
The government said the projects would create nearly 250 jobs - 171 in Kent, 47 in Sussex and 31.5 in Cumbria - and attract £1m from other private and public bodies.
Thanet District Council's cinema scheme will bring an "iconic but derelict" Art Deco building that forms a critical part of the Dreamland amusement park site back into use, the cabinet office said.
The scheme includes creating a commercially-viable, high-quality restaurant in the 1930s Grade II listed building, and restoration of the original cinema facade.
The riverbank scheme by Arun District Council will complement a new £14m flood defence scheme led by the Environment Agency, and aims to improve links between Littlehampton town centre, the sea front and riverside.
A 10-month project in Whitehaven will see Rosehill Arts Trust create a new contemporary arts centre at the Rosehill Theatre.
Plans include creating a new theatre entrance and front of house, an exhibition space, an enlarged foyer, and a renovated auditorium, foyer and dressing rooms.
