    Belfast
    Belfast, the capital of Northern Ireland, lies where the River Lagan flows into Belfast Lough. The city is home to around 341 thousand people, while the Greater Belfast conurbation has more than 671 thousand. In the 17th century Belfast became a trading centre thanks to an influx of settlers from England and Scotland. It is known for its shipbuilding and textile industries. A temperate maritime climate means mild winters and cool summers. Belfast is best visited in spring or summer, when temperatures are pleasant.
