St Crumnathy's Cathedral
Achonry, County Sligo
'Upon this site the holy saints of old did walk'. These words are inscribed on the bishop's throne that once took pride of place within the walls of St Crumnathy's Cathedral. These words are a reflection of the locality's past association as a site of pilgrimage, long before the present edifice was constructed. Religious association with this site dates back to the 6th century with St Finnian of Clonard. It was a centre of learning and piety, guided by St Nathy Crumthir, whose most notable student was St Feichin.
The present Church of Ireland cathedral was constructed in 1822 and dedicated to St Nathy. It ceased functioning as a cathedral in 1997 and was officially deconsecrated in 1998.
