Overview
The River Aherlow (Irish: An Eatharlach) winds through the Glen of Aherlow, a verdant valley sandwiched between the towering Galtee Mountains to the south and the wooded ridge of Slievenamuck to the north. Rising near Anglesborough in County Limerick, the river flows west, north and east, forming a five‑kilometre stretch that marks the Limerick‑Tipperary border before joining the River Suir at Kilmoyler. The glen, whose name derives from the old Irish eatharlach – “lowland between two high lands” – is dotted with the villages of Lisvarrinane, Bansha and Galbally and is centred around the Christ the King statue, erected in 1950, which crowns the entrance to the Glen of Aherlow Nature Park.
History & Background
For centuries the glen served as a vital pass linking the provinces of Limerick and Tipperary, shaping settlement patterns and transport routes. Bridges such as the historic five‑arch Ashgrove Bridge and the modern N24 crossing illustrate the river’s long‑standing role in local connectivity. Folklore records that 17th‑century historian Geoffrey Keating hid in a cave here while compiling Foras Feasa ar Éirinn. The Heritage Trail weaves together sacred and historic sites – St Pecaun’s Holy Well, a Celtic ogham stone, the 15th‑century Franciscan friary of Moor Abbey and the megalithic passage tomb known as Darby’s Bed – all sign‑posted along the walking routes.
