The Story of the Larne Name

The name Larne comes from the Irish Latharna, the name of an ancient territory in this part of County Antrim. Patrick Weston Joyce traced the name to Lathair, traditionally identified as the son of Hugony the Great, a legendary early king of Ireland. The territory of Latharna once extended considerably farther than the modern town, reaching northward toward Glenarm.

The settlement itself was historically known as Inver-an-Laharna, meaning the river-mouth or estuary of Latharna, because it stood at the mouth of the river flowing into what is now Larne Lough. The modern Irish name, Latharna, is still the official Irish form recorded by the Placenames Database of Ireland.

Larne's position on the coast has shaped its history from the beginning. Its sheltered lough made it a natural harbor and a gateway between Ireland and Scotland. The area was already important in medieval times, and the old castle of Olderfleet, standing on the tip of the Curran peninsula, guarded the entrance to the lough. Samuel Lewis recorded that the fortress was traditionally associated with the Scottish Bisset family, who established themselves along this part of the Antrim coast.

Larne also occupies an intriguing place in the story of Scotland and Ireland. In 1315, Edward Bruce, brother of Robert the Bruce, landed at Larne with an army of approximately 6,000 men during his campaign to establish a Scottish kingdom in Ireland. The expedition would eventually bring much of Ulster into a period of warfare and upheaval.

By the nineteenth century, Larne had become an important market town and seaport. Its harbor supported trade in commodities including limestone and rock salt, while its position on the coast made it one of the principal maritime gateways of Antrim. Contemporary visitors admired the beautiful setting of the town around the lough, with Island Magee rising across the water.

That maritime role would become even more important in modern times. Larne developed into one of Ireland's principal ferry ports, strengthening the ancient connection between this corner of Antrim and the Scottish and wider British coasts.

But the oldest layer of the name reaches much further back. Latharna was not originally the name of a modern town at all—it was the name of a territory. The town inherited the ancient name because it grew beside the river mouth that served as its natural gateway.

Larne is therefore a wonderful example of an Irish town whose name carries the memory of an entire ancient territory, while its location has continued to make it a gateway between Ireland and the wider Irish Sea.
