Built in the years after Emancipation
The Church of the Assumption
The Catholic church at Ahiohill, the Church of the Assumption of Our Lady, dates from around 1825 and was dedicated for worship in 1832 - within a few years of Catholic Emancipation in 1829, when building a Catholic church in the open was a new freedom. It sits in the parish of Enniskeane and Desertserges in the Diocese of Cork and Ross. Father Maurice Roche, appointed parish priest of nearby Desertserges in 1817, supervised the building and served until his death on 11 April 1839; he is buried just beside the southern wall of the church he raised. It is a working parish church, not a heritage attraction, but it is the oldest thing in the village and the reason the village is where it is.
A junior club that does a double
St Oliver Plunkett's GAA
The local GAA club, St Oliver Plunkett's, was founded in 1974 and named for the saint canonised that same year, though there are records of games being played at Ahiohill as far back as the famine years of the 1840s. It fields hurling and football teams in the Carbery divisional board of Cork GAA. In 2023 the club pulled off a county confined junior B double - the footballers beating Ballyphehane and the hurlers taking Ballyclough a week later. For a village of this size that is a remarkable haul, and the new pitch and walkway at the club complex is the kind of thing a parish builds with its own hands. January is the busiest month in the pub because of it.
