Thurles (pronounced /θɜɹlɛs/, or locally /tɜrləs/; Dúrlas Éile) is a town in County Tipperary, Ireland, situated on the River Suir, with a population of around 8,000. It is twinned with Bollington in England and Salt Lake City, Utah, United States.
The town itself owes its development to the Norman Butlers and particularly to James Butler, who was created Earl of Ormond by Edward III in 1328. Two of the original family fortresses still remain in Thurles today.
Thurles is the birthplace of the Gaelic Athletic Association, founded in 1884 in Hayes' Hotel. Semple Stadium, where the centenary All-Ireland hurling final was played, is the second largest Gaelic Athletic Association stadium in Ireland, second only to Croke Park. In addition, Lar na Pairce, a museum devoted to the Gaelic Athletic Association, is located in the town. Semple Stadium in Thurles is Ireland's second largest sports arena with a capacity of 55,000. It is the spiritual home of Munster hurling and many famous matches, especially Munster Finals, have been played there. It was also the site of the Féile rock festival during the 1990s.
Thurles has a well-developed industrial sector originally based on the traditional agri-based sector. It has also successfully attracted modern high technology industries to the area, with the establishment of the Thurles Technology Park.
