Letterkenny , known as the Cathedral Town, is the largest and most populous urban settlement in County Donegal. Its English name is derived from the Irish name Leitir Ceanainn, meaning "Hillside of the O'Cannons" – the O'Cannons being the last of the ancient chieftains of Tír Conaill. With a population of 19,588, Letterkenny is located on the River Swilly in east Donegal. Along with the nearby city of Derry, Letterkenny forms the major economic core of the north-west of the island of Ireland.
The modern urban centre of Letterkenny began as a market town at the start of the 17th century, during the Plantation of Ulster. An ancient castle once stood near where the Cathedral of St. Eunan and St. Columba, Donegal's only Roman Catholic cathedral, stands today. Letterkenny Castle, built in 1625, was located south of Mt Southwell on Castle Street. Donegal's premier third-level institution, the Letterkenny Institute of Technology (LYIT), is located in the town, as are Saint Eunan's College, Highland Radio, and the only Hindu temple in the Republic of Ireland. Letterkenny is also the original home of Oatfield Sweet Factory, the confectionery manufacturer, and is renowned for its night-life, with enterprises such as Club Voodoo, The Grill, Milan and The Pulse regularly attracting international names. The Aura Complex, near O'Donnell Park, includes an Olympic-standard swimming pool, which is situated on the Glenties Road, the Danny McDaid Athletic Track and an arena capable of hosting top-level events.
Letterkenny is a Canadian television sitcom created by Jared Keeso and Jacob Tierney, that debuted on CraveTV in February 2016, and later also aired on The Comedy Network. The show stars Keeso and Nathan Dales as Wayne and Daryl, two friends living in the small town of Letterkenny, Ontario, a fictional community loosely based on Keeso's own hometown of Listowel, Ontario. On March 10, 2016, Letterkenny was renewed for a second season.
