Place & story

The castle and the trading street

A thirteenth-century castle gave Castleisland its name, appearing in medieval references as the Castle of the Island or simply the Island. A surviving tower behind Killarney Road remains part of the castle grounds. The town developed as a commercial centre for its agricultural hinterland, and its unusually broad Main Street preserves the scale of a market street. Its protected buildings include the Carnegie building, Presentation Convent and older commercial premises, recording several phases of that development. [2]

People & connections

Pádraig O'Keeffe's teaching system

Pádraig O'Keeffe came from Glountane near Castleisland. After leaving school teaching in 1920, he travelled through Sliabh Luachra teaching fiddle and accordion. He devised notation suited to his pupils: fiddle strings corresponded to spaces on the staff, with numbers indicating fingering, while accordion notation included bellows directions. Manuscripts preserved by former pupils and their families now form part of the Irish Traditional Music Archive. They record the practical methods by which an influential regional musician passed tunes to another generation. [3]

A church built in stages

The Catholic church of Saints Stephen and John began in 1880. Its Gothic Revival design combines a cruciform plan, slate roofs and carefully worked limestone. Inside, pointed arcades rest on polished granite columns with marble bases. Around 1910 a three-stage tower and broach spire were added, giving the church a more prominent skyline. Later sacristy and mortuary-chapel additions extended the building again, leaving several generations of work within the same ensemble. [4]
