Bangor is at the heart of North Down in Northern Ireland along with the smaller nearby suburb of Holywood. The prosperous seaside town on the "Gold Coast", just 12 miles from Belfast, and connected to the city by train, has a population of some 55,000, quite large by local standards. A monastery was founded in the area in the sixth century known throughout Ireland for centuries, and Bangor was well known for its choral music and learning. In more recent times cotton mills were the source of great wealth in Bangor, whose influence eventually declined to be superseded by tourism. Places to see in North Down include Bangor Marina, Clandeboye Park and the Somme Heritage Centre.
