County Carlow Guide (Ceatharlach)

“The Barrowsiders” - in the province of Leinster. County town: Carlow.

Ireland’s second-smallest county, on the River Barrow, with a 5,000-year-old dolmen at Brownshill.

One of Ireland’s smallest counties, Carlow sits in the fertile valley of the River Barrow in the south-east. It’s quietly historic - the 5,000-year-old Brownshill Dolmen has one of the heaviest capstones in Europe - and increasingly known for good food, river walks and a lively county town. Easy to overlook, and all the better for it.

Wedged between the Blackstairs Mountains and the fertile valley of the River Barrow, Carlow is Ireland's second-smallest county, yet it punches well above its size in history. Granite from its uplands built much of Leinster, and the county's ancient nickname, the Dolmen County, comes from the Browneshill portal tomb outside Carlow town, whose colossal capstone is reckoned the heaviest in Europe. The Barrow, Ireland's second-longest river, threads the county from north to south, and its towpath, once walked by horses hauling grain barges to Waterford port, is now one of the country's loveliest long-distance trails.

Carlow town grew rich on milling and malting, and in 1926 it became the home of the Irish Free State's first sugar beet factory, an industry that shaped local farming for seventy years. The county has a strong scholarly streak too: Carlow College, founded in the 1780s, is among the oldest Catholic institutions of higher learning in Ireland, and the town now hosts a campus of the South East Technological University. For visitors tracing roots, the graveyards of Leighlinbridge, St Mullins and Clonegal sit in some of the most tranquil river scenery in the country.
