The interactive exhibition on the east side of City Hall’s ground floor will highlight the history of the city through a range of themes including its industrial past, significant events, language and its famous citizens.
Lord Mayor of Belfast, Alderman Brian Kingston, said: “Belfast City Hall has become one of the city's leading visitor attractions and this fascinating exhibition will further enhance the City Hall experience.
"We’re currently welcoming 70,000 visitors annually, and I’m looking forward to seeing footfall rise as a result of this development."
There will be some disruption during the construction phase. The Donegall Square East entrance will close from Monday 12 September and the popular Bobbin Coffee Shop will close from Sunday 2 October until early 2017.
