St Patrick's Cathedral, Killala, Anglican cathedral in Killala, Ireland

St Patrick's Cathedral in Killala is one of Ireland's smallest cathedrals: a long rectangular nave of four bays, about 32 m by 10 m, with gable ends, a square tower and spire at the west end, and a gabled vestry at the north end. A staircase leads to a gallery, and the nave holds boxed pews and a Telford organ dated 1838.

The episcopal seat dates back to around 434 to 441 when Saint Patrick established a church here and appointed Saint Muredach as the first bishop. From these early Christian foundations, the site remains an important place of worship in the region.

The cathedral serves the local Anglican community and shapes religious life in this small town. People gather here for services and celebrations that give the place its spiritual character.

The cathedral stands on the Ballina to Ballycastle road in Killala, so it is reached by road rather than on foot from a town centre. The nave measures 32 m by 10 m, and a staircase inside leads up to the gallery. The graveyard holds the 9th-century souterrain, whose chambers are underground.

Underground chambers dating from the 9th century lie beneath the cathedral graveyard. This archaeological discovery makes the place a layered record of different periods in one location.
