Overview
Letterkenny is Donegal’s largest town, around 22,000 people, and it works best as a base rather than a day out in itself: the set-piece sights fill an afternoon, but Glenveagh, the Fanad and Inishowen headlands and a string of Blue Flag beaches all lie within an hour’s drive. The town sits where the River Swilly runs down through a glacial valley into Lough Swilly, one of Ireland’s few fjords. Its Irish name, Leitir Ceanainn, means “hillside of the O’Cannons” – the clan who ruled Tír Conaill until 1250.
History & Heritage
The town grew out of the Plantation of Ulster in the early 1600s, when the Scottish captain Patrick Crawford was granted 1,000 acres and laid out a market at the first crossing point of the River Swilly. An original stone castle, built in 1625, once stood where the cathedral now rises, though no visible ruins remain.
Its position put it in the path of dramatic history. During the 1798 Rebellion, French forces attempting to land troops in Donegal were intercepted by the Royal Navy, and the captured United Irish leader Theobald Wolfe Tone was held at Laird’s Hotel on Main Street before his transfer to Derry. A plaque near the Market Square marks the episode. In the 19th century the nearby Port of Ballyraine took in ships carrying iron and salt, while local farmers shipped out butter and hides.
The town’s pride shows in its upkeep. In 2015 Letterkenny was judged Ireland’s tidiest town, a title earned through decades of landscaping and civic effort, and you see it in the tree-lined promenades and the kept parks along the riverbank.
What to See & Do
Architecture & Landmarks
The skyline belongs to the Cathedral of St Eunan and St Columba, built between 1890 and 1901 in a light Victorian neo-Gothic style. As the tallest building in Donegal, it carries intricate stained glass by Michael Healey. The nave is open to visitors through the week, though not until after 1pm on Sundays. Directly opposite stands Conwal Parish Church, a Church of Ireland building with structural elements dating to the 17th century.
Further down from the Market Square, Mount Southwell Terrace is a run of Georgian red brick from 1837 that once served as a holiday residence for the poet and activist Maud Gonne. Nearby, the modern council offices – known locally as “The Grasshouse” for their sloping green roof – have drawn architectural interest since they went up.
Museums, Arts & Culture
If you have time for one indoor stop, make it the Donegal County Museum, housed in the former 1845 workhouse on High Road. It’s free, holds some 8,000 artefacts spanning prehistory to the present, and keeps the North West Film Archive. It opens Monday to Saturday, afternoons only on Saturdays.
For art, Glebe House and Gallery, 18 km west, is the former home of the painter Derek Hill; the collection runs to works by Picasso, Braque and Renoir, and the gardens (open daily 10am–6pm) are free. One caveat: the house and gallery were closed for conservation through 2024 and into 2025, with the grounds reopening first – ring ahead before making the drive out.
Live performance runs at An Grianán Theatre, the county’s largest venue at 383 seats, which hosts the Earagail Arts Festival in June and July. Just behind it, the Regional Cultural Centre puts on concerts, screenings and exhibitions.
Outdoor Attractions & Nature
Just outside the centre the landscape turns quickly to wild Donegal. A five-kilometre drive north on the Churchill Road brings you to Newmills Corn and Flax Mills, which runs one of Ireland’s largest working waterwheels alongside a historic forge and flax mill.
For a quiet walk, Ballyarr Wood Nature Reserve (about 5 km out) has marked circular trails through semi-natural oak woodland, with badgers, roe deer and buzzards about. To the east, the Manorcunningham Viewpoint (7 km on the Derry road) looks out across Lough Swilly. In the town itself, St Eunan’s Park and Riverbank Park give you riverside paths, playgrounds and free parking.
Markets, Food & Drink
The Letterkenny Farmers Market runs every Saturday morning on the High Road: local produce, artisan breads, cheeses and crafts. For a proper Donegal breakfast, Quiet Moment Tea Room on Main Street is known for its scones. At the top end, the Michelin-recommended Lemon Tree does fine dining, while Yellow Pepper on Lower Main Street keeps a relaxed à-la-carte menu.
Evenings centre on Main Street and the Cathedral Quarter. Traditional pubs like The Cottage Bar, McGinley’s and Blake’s are the ones for live trad, with plenty of cafés and international restaurants in between.

The best of Letterkenny is really the country around it. Give the town a morning – the cathedral, the free museum and a walk along the Swilly – then point the car at Glenveagh or the Fanad beaches for the afternoon, when the light over Lough Swilly is at its clearest.
