Cathedral Church of St. Fachtna, Anglican cathedral in Rosscarbery, County Cork, Ireland

The Cathedral Church of St. Fachtna is located in Rosscarbery and is the smallest cathedral in Ireland, built with a cruciform layout. Its architecture blends Gothic and Georgian styles in a compact structure that remains fully functional.

The site originates from the 6th century when St. Fachtna founded a monastery here that became the main religious center of West Cork. The building underwent major reconstruction following damage sustained during conflicts in the 1600s.

The name Ross comes from Ros Ailithir, "wood of the pilgrims", the monastic site Fachtna founded in the late sixth century, where Brendan the Navigator taught. The cathedral holds a ring of six bells in G, regularly rung; the tenor weighs 636 kg. Its tower is the only one in Ireland with a ringers' gallery, so the ringing can be watched from the congregation.

The west doorway beneath the tower is Romanesque in style, while the rest of the building mixes Gothic and Georgian windows with wooden casements under stone lintels. The ring of six bells in G, tenor 636 kg, is regularly rung from a ringers' gallery, so the ringing can be watched from inside.

The tower holds Ireland's only bell-ringers' gallery, letting the congregation watch the ring of six bells in G being rung; the tenor weighs 636 kg. Storms blew the top of the spire off twice, in the winter of 1886 and again in February 1923.
