Belfast is the capital and largest city of Northern Ireland, standing on the banks of the River Lagan on the east coast. It is the 12th-largest city in the United Kingdom and the second-largest on the island of Ireland.
By the early 19th century, Belfast became a major port. Shipbuilding was a key industry; the Harland and Wolff shipyard, which built the RMS Titanic, was the world’s biggest shipyard.
Belfast is still a port with commercial and industrial docks, including the Harland and Wolff shipyard, dominating the Belfast Lough shoreline. It is a Gamma global city in 2018.
