Letterkenny

Letterkenny (Leitir Ceanainn ˈl̠jɛtjəɾj ˈcanɣən̪ɣ, meaning "hillside of the O'Cannons"), nicknamed the Cathedral Town, is a large town in County Donegal, Ireland, on the River Swilly in the north-west of Ulster. Along with the nearby city of Derry, Letterkenny is a regional economic gateway for the north-west of Ireland. Letterkenny began as a market town at the start of the 17th century, during the Plantation of Ulster. A castle once stood near where the Cathedral of St Eunan and St Columba, County Donegal's only Catholic cathedral, stands today. Letterkenny Castle, built in 1625, was located south of Mt Southwell on Castle Street. County Donegal's largest third-level institution, Atlantic Technological University (ATU) Letterkenny, is located in the town, as are St Eunan's College, Highland Radio, and a Hindu temple. Letterkenny was also the original home of Oatfield Sweet Factory, a confectionery manufacturer; the factory closed and was demolished in 2014. In 1798, Theobald Wolfe Tone was arrested at Laird's Hotel in the town. In 2015, Letterkenny was judged as the tidiest town in Ireland. Letterkenny takes its name from the Irish Leitirceanainn, meaning "Hillside of the O'Cannons" – the O'Cannons being the last of the ancient chieftains of Tír Conaill. While no evidence of forts or castles belonging to the O'Cannon clan exists in the Letterkenny district, eight miles west of Letterkenny is located Doon Rock, believed by some to be an ancient inauguration site of the O'Cannon Kings. The O'Cannon dynasty is descended from Conn of the Hundred Battles and Niall of the Nine Hostages, two of Ireland's ancient High Kings. The O'Cannons have been described as 'Ancient Princes of Tír Connaill' and 'Valiant Chiefs'. Their 350-year dynasty in Tír Connaill ended in 1250. Their ancient territory is recorded as being in Tír Aeda (now the barony of Tirhugh) in what is now South Donegal. After the deaths of Ruairí Ó Canannain (Rory O'Cannon) and his son Niall Ó Canannain in 1250, the sept declined greatly in power.
