About Belfast

Belfast 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 2020 of about 630,000. It's had a troubled history but is nowadays safe to visit and has the best-developed visitor facilities in Northern Ireland. And its situation means that Belfast can confidently claim to be the most fascinating city in both the United Kingdom and on the island of Ireland.
