Place & story

A Carmelite foundation

John de Barry founded the Carmelite priory at Castlelyons in the early fourteenth century. His family already had a substantial record of supporting religious houses in Cork. The surviving remains belong largely to the fifteenth century. After the Reformation the property passed to Richard Boyle, first Earl of Cork, who granted it to his daughter Alice. The Office of Public Works undertook conservation in the 1930s, preserving the remains as a national monument. [2]

Windows, a school and a ball alley

The priory's later history was unusually varied. In 1638 windows were taken from Castlelyons for the Earl of Cork's renovation of Lismore Cathedral. The site also became a hedge school. By the middle of the nineteenth century, the antiquarian John Windele found the nave being used by villagers as a ball alley. These changes carried the old religious buildings into the everyday life of later Castlelyons, with learning and recreation occupying spaces originally made for worship. [3] [2]

People & connections

An tAthair Peadar at Castlelyons

Peadar Ó Laoghaire served as parish priest from 1891 until his death in 1920. Known nationally as an tAthair Peadar, he became an important writer in the Irish-language revival, encouraged by the Gaelic League and by Seosamh Laoide. In Castlelyons he spoke Irish with older parishioners who still used the language. His literary work thus developed alongside his everyday parish duties. He died in the parochial house on 21 March 1920 and was buried in the churchyard of Saint Nicholas. [4]

Thomas Kent's return home

The Kent family's home at Bawnard, near Castlelyons, became the scene of an armed confrontation with police in May 1916. Head Constable Rowe was killed; David Kent was wounded, and Richard Kent was fatally shot while attempting to escape after the surrender. Thomas Kent was court-martialled and executed at Cork Detention Barracks on 9 May. In 2015 his remains were identified through DNA testing. His state funeral took place at Saint Nicholas's Church on 18 September, followed by reinterment in the adjacent family plot. [5] [6]
