Witshire's Trowbridge Town Hall is set to undergo a £8.1m redevelopment next year.
Half of the £16.3m given to Trowbridge from the Future High Streets Fund will go towards restoring the Grade-II listed building's ballroom and creating three smaller performances spaces.
The venue hosts film, music, visual arts and theatre events, welcoming 50,000 visitors annually.
Director David Lockwood hopes the project will reimagine a town centre with community ownership and culture at its heart.
"The Town Hall opened over 100 years ago and pledged ‘for the benefit of the inhabitants of the town for ever.’ A century on, we’re inspired by that history to create a pioneering cultural venue which is deeply rooted in its community."
