Larne is a substantial seaport and industrial market town on the east coast of County Antrim, Northern Ireland with a population of 18,228 people in the 2001 Census. As of 2011, there are about 31,000 residents in the greater Larne area. It has been used as a seaport for over 1,000 years, and is today a major passenger and freight roll-on roll-off port. Larne is twinned with Clover, South Carolina. Larne is administered by Larne Borough Council. Together with the neighbouring district of Carrickfergus and part of Newtownabbey, it forms the East Antrim constituency for elections to the Westminster Parliament and Northern Ireland Assembly. The coastal area around Larne has been inhabited for millennia, and it thought to have been one of the earliest inhabited areas of Ireland, with these early human populations believed to have arrived from Scotland via the North Channel. The early coastal dwellers are thought to have had a sophisticated culture which involved trading between the shores of the North Channel and between other settlements on the coasts of Scotland.
