Overview
Castlemahon – officially Mahoonagh – sits on the fertile Golden Vale of County Limerick, four kilometres south‑east of Newcastle West and on the east bank of the River Deel. Its single main street is lined with a primary school, a Roman‑Catholic church, a pub, two shops, a car garage, a plant‑hire business and a small industrial estate, giving the settlement a cosy, self‑contained feel. The village is a natural gateway to historic sites, gentle hills and riverside walks, offering visitors an authentic slice of Irish life.
History / Background
- Name – Mahoonagh comes from the Irish Maigh Tamhnach meaning “the plain of the tree‑stumps” or “the plain of clearings”. The English name Castlemahon derives from the ruins of the large square tower that dominate the skyline.
- Early medieval period – The area is recorded as the scene of two royal deaths: King of Cashel Cellachan in 954 and King of Munster Cormac MacCarthaigh, who lived here as Cormac Muighe Thamhnach before being killed in 1138.
- 15th‑century fortification – Around 1490 the Fitzgerald family erected a high square tower (≈ 12 m) and a nearby circular stone building with a conical roof. The tower later passed to the Fitzgibbons and remains the most striking landmark.
- Religious heritage – An Augustinian abbey was founded circa 1499. It was destroyed in a 1579 raid, killing over forty monks and civilians. The ruins lie in the graveyard adjoining the present St John the Baptist church, which was rebuilt in 1961 on the site of the 19th‑century St Nicholas’ church.
- 19th‑century development – A co‑operative dairy society was established in 1890, and a poultry processing plant later became a major employer until its closure in 2006.
- Notable people – The village produced emigrants such as poet Michael Scanlan (“the Fenian Poet”) and Thomas Scanlan, mayor of Houston, Texas, in the 1800s.
- Modern folklore – In November 1990 two Siberian tigers, Nova and Batack, were temporarily housed in a reinforced cage built for them by a local family – an episode even mentioned in a Dáil debate in 1992.
