The Irish name says it before anything else: Cathair Dun Iascaigh, the town of the fort of the fishery. Cahir takes its name from the great stone ringfort - the cathair - that gave way, in the twelfth century, to a Norman castle on an island in the River Suir. The castle is still there. It is one of the best preserved medieval fortresses in Ireland: keep, six towers, thick curtain walls, all sitting on rock in the middle of the river. The Earl of Essex bombarded it in 1599 with cannon and culverin. Oliver Cromwell took it in 1647. Every time it has fallen, it has been rebuilt. In a country that loves ruined castles, Cahir has a complete one. The small heritage town that grew around it sits at the meeting place of two mountain ranges, on the road from Dublin to Cork, in a piece of Tipperary that has been a crossing-point since before the Normans arrived.
The first builders who chose this spot were not Anglo-Normans. They were prehistoric people who raised a circular stone ringfort - a cathair - on a small island in the Suir. The river ran fast around the rock, the fish were good, the road north and south crossed here. When the Anglo-Normans arrived in the twelfth century, the strategic logic was unchanged; they put a castle on the same island. By the fifteenth century it had become the seat of the Butlers, Barons of Cahir, a junior branch of the great Butler dynasty that ran south Munster from Kilkenny and Ormond. The castle today preserves work from many centuries - the keep, the great gatehouse, the curtain walls and towers - much of it 13th- to 15th-century in date. A cannonball is still lodged in the wall of the main tower, fired in the 1599 siege by the Earl of Essex's gunners and never since removed.
Cahir, along with Clonmel, was the centre of South Tipperary's Quaker population. The Quaker families - Grubb, Going, Walpole - built their meeting house on Abbey Street in 1833 and ran the local milling trades for the next century. The town was an early stop on Charles Bianconi's stagecoach network: the Italian-born entrepreneur began running coaches between Clonmel, Cahir, and Cashel in the early nineteenth century, and the building that now houses The Galtee Inn, on the square, was his Cahir stopping place. The town also has one of only three churches that the famous English architect John Nash designed in Ireland - a Church of Ireland parish church, still in use, that quietly carries his Regency Gothic touch on Castle Street. Nash is better known for Buckingham Palace and Regent Street. He worked for Lord Cahir on the castle too.
About a mile downstream from the castle, on a wooded slope above the Suir, stands one of Cahir's stranger buildings: the Swiss Cottage, a thatched ornamental cottage orne designed by John Nash for Richard Butler, 1st Earl of Glengall, around 1810. It is not a Swiss building. It is an English Regency fantasy of what a Swiss building might look like - all curving thatched roof, rustic verandahs, irregular asymmetry - meant to give the Glengalls and their guests a place to picnic and play at the picturesque. The Earl's wife, Emily, decorated the interior with imported Dufour wallpaper. The cottage fell into ruin after the family lost the estate in the nineteenth century and was rescued in the 1980s by the Office of Public Works. It is now open to visitors. Walking the woodland path from the town to the cottage along the river is one of the most pleasant things to do in Cahir.
The town sits in a hollow between two of Ireland's significant mountain ranges. The Galtee Mountains form the largest inland range in the country, rising sharply to the northwest with Galtymore at 919 metres. The Knockmealdown Mountains stand to the south, lower but darker, forming the border with Waterford. South-west of the town lie the Mitchelstown Caves - one of Europe's finest cave systems, complete with strange dripstone formations and a long-running tradition of guided tours by the McGrath family who own the land above them. Within Cahir itself the salmon weir, just downstream from the castle bridge, is a popular fishing spot. The Glengarra Wood walk in the Galtees draws weekend hikers. The town's other entries on the tourist circuit include a Downhill and Enduro mountain-biking track, an 18-hole golf course, and the wide range of heritage walks that work outward from the square.
Like every Tipperary town, Cahir has its share of revolutionary history. Marian Tobin, born in 1870, ran a safe house in the area during the Irish War of Independence; her place was a critical refuge for IRA flying columns in the south Tipperary brigades. Michael Murphy, born in Cahir in 1831, was awarded the Victoria Cross for service in the Indian Mutiny - and then had it forfeited for later crimes, one of the only Irishmen ever to have the medal taken back. Edmund Keating Hyland (1780-1845), the great uilleann piper, was born here and has his statue in the main square. The town has also produced more peaceful contemporary figures - Tommy O'Donnell the Munster and Ireland rugby player, the comedy duo The 2 Johnnies. Cahir today is bypassed by the M8 motorway and the realigned N24, so the traffic that used to choke its medieval streets now flows around it. The castle sits on its island. The Swiss Cottage stands in its wood. The mountains hold the horizons.
Cahir sits at 52.38 N, 7.93 W in County Tipperary, on the River Suir between the Galtee Mountains to the north (Galtymore 919 m) and the Knockmealdowns to the south. Waterford (EIWF) is 32 nm east-southeast; Cork (EICK) 36 nm southwest; Shannon (EINN) 48 nm north-northwest. Recommended viewing altitude 2,000-3,000 ft AGL. From the air the castle is unmistakable - a fortified island in the river, with the medieval bridge, the modern town square, and the heritage core of narrow streets clustered around it. The Swiss Cottage is 1 mile (1.5 km) downstream in woodland. The bypass roads (M8 west, N24 north and east) form a clear ring around the historic core.
