Charleville, as its name suggests, was a plantation town, founded by Roger Boyle, Lord Orrery in the year after the restoration of King Charles II. However, it is as the seed-bed of nationalist poets, prelates and patriots that Charleville is most famous. It was the birthplace of Seán Mac Domhnaill and Daniel Mannix. Éamon de Valera walked from the nearby townland of Bruree to school there each day.
The beautiful Church of the Holy Cross is only 110 years old. Canon Lebocq of the Institute of Christ the King, based in Limerick, was the celebrant of a wonderfully reverent Mass.
