Dublin (pronounced /ˈdʌblɨn/; locally [ˈdʊblən] or [ˈdʊbələn]) is the primate and capital city of Ireland. It is officially known in Irish as Baile Átha Cliath [bˠalʲə aːha klʲiəh] or Áth Cliath [aːh cliə(ɸ)]. The English name comes from the Irish Dubh Linn meaning "black pool". It is located near the midpoint of Ireland's east coast, at the mouth of the River Liffey and at the centre of the Dublin Region. Originally founded as a Viking settlement, it evolved into the Kingdom of Dublin and became the island's primary city following the Norman invasion. Today, it is ranked 23rd in the Global Financial Centres Index, has one of the fastest growing populations of any European capital city, and is listed by the GaWC as a global city with a ranking of Alpha, placing Dublin among the top 25 cities in the world. Dublin is a historical and contemporary cultural centre for the country, as well as a modern centre of education, the arts, administration, economy and industry.
