22–24 August 2025

Kiltullagh, Athenry, Co. Galway

Part of National Heritage Week 2025

Join Kiltullagh Killimordaly Heritage Society as we celebrate D’Arcy 300, a weekend of events to commemorate 300 years since the birth of Patrick D’Arcy (1725–1779) a renowned mathematician, scientist, and military man.

Patrick’s early life at Kiltulla House was shaped by his family’s Catholic faith, their support for the Jacobite cause, and the harsh reality of the Penal Laws. At just fourteen years old, he left rural Ireland for France. In Paris, he went on to make lasting contributions to his fields of study.
