The free event at Hastings Register Office, based at Hastings Town Hall, on Sunday, November 4 from 10am to 2pm, will allow people to find out more about the ceremonies and services on offer from East Sussex Registration.
People will be able to view the two unique ceremony rooms which host weddings and civil partnerships as well as other ceremonies such as renewals of vows and naming celebrations.
They will also be able to speak to local ceremony suppliers about their products and services, while registrars and celebrants will be on hand to answer questions and take bookings.
The Register Office moved to the Grade II-listed Town Hall in January 2016 from its previous base in the Summerfields complex in Bohemia Road.
Cllr Bill Bentley, East Sussex County Council lead member for communities and safety, said: “The open day is a unique opportunity for people to gain an insight into the wide range of ceremonies and services on offer.
“Being able to offer weddings and other ceremonies in such attractive surroundings in a building with such a rich heritage is a real asset to the registration service.
“The event will offer people the chance to have a look round and to envisage how their special day could look at a venue which is drenched in history and provides a stunning backdrop.”
Hastings Register Office offers ceremonies in the Council Chamber, which holds up to 60 guests, and the smaller Mayor’s Parlour, which can accommodate 12 guests in a more intimate setting.
People can find out more about ceremonies and other registration services online at www.eastsussex.gov.uk/ceremonies or by calling 0345 60 80 198.
