About Belfast

Belfast (Irish: Béal Feirste) is the capital and largest city of Northern Ireland. Most of it historically lay in County Antrim west of the River Lagan, with about a third on the east bank in County Down, but it's always been governed as a separate metropolis, with a population in 2024 of about 671,000. It's had a troubled history but is nowadays safe to visit and has the best-developed visitor facilities in Northern Ireland.
