Brighton Dome has been given a £3 million boost towards a major refurbishment project.
The grant from the Coast to Capital Local Growth fund will go towards the redevelopment of the Corn Exchange and studio, which are among the main venues for the Brighton Festival.
Works began this month and are due for completion in late 2018.
The grade I-listed Corn Exchange’s heritage features will be restored as part of the project, which will also increase its capacity.
The studio space will also benefit from balcony seating, a new artists’ creation space and a bar and cafe.
The £3 million grant means that £19.3 million of the overall £21 million costs are now in place. Fundraising will continue in order to generate the remaining money.
The overall project aims to reaffirm Brighton’s Royal Pavilion Estate as a key cultural destination “by equipping it for a sustainable future”.
Brighton Festival chief executive Andrew Comben said the most recent grant was a “fantastic endorsement” of the vision.
“This creates a really strong foundation with which to launch our public appeal in the coming months,” he added.
Brighton and Hove City Council leader Warren Morgan added: “The city has an international reputation for its fantastic arts and culture offer and this is something we’re keen to maintain and build on for the benefit of all our communities.”
The council recently advertised a new culture tsar role, whose main responsibilities will include overseeing the transfer of the Royal Pavilion and Museums’ sites to a new charitable trust.
