For much of the twentieth century, Cahir stood at an intersection of two busy national roadways: the Dublin to CorkN8, and the Limerick to WaterfordN24. The N8 was realigned in 1991 to run west of the town, while the old road through it was renumbered the R670. Traffic from the N24 still left the town badly congested, however, until October 2007 when this road was also realigned to bypass Cahir to the north and east. The same road improvement scheme saw major changes to the N8 corridor: a new motorway, the M8, was constructed west of the town between 2006 and 2008. Access to Cahir from this motorway is gained at Junctions 10 and 11. Cahir is on the Limerick–Waterford railway line. The town's railway station opened on 1 May 1852. There are two trains a day to Tipperary and Limerick Junction and two to Clonmel, Carrick on Suir and Waterford. There is no Sunday service. Bus Éireann runs regular services to Dublin, Cork, Limerick and Waterford through the town.
History
The name Cathair or an Chathair translates as "stone ringfort", while the name Cathair Dún Iascaigh means "town of the fort of the fishery". In older accounts, it was often spelled "Caher". Cahir Abbey was established in the late 12th century. For much of its history, the town has been influenced by the Butler family. It was from this family that the first Barons of Cahir were created. It was known for much of its history as being a defence town. Cahir, together with Clonmel, were the centres in South Tipperary of the Quaker population, who constructed a meeting house in Abbey Street in 1833. The principal Quaker family names, largely engaged in milling, were Grubb, Going and Walpole. It was one of the first towns to be linked by stagecoach in the nineteenth century, when Charles Bianconi commenced services between Clonmel, Cahir and Cashel. The building at The Square, where The Galtee Inn is now sited, was the stopping point in the town for Bianconi's coaches.
