The Annals of Lough Ce summed up the catastrophe in one stark sentence: the great church of Tuam-da-Ghualann fell in one day, both roof and stone. Almost everything was lost. But the chancel arch - a single, perfectly circular Hiberno-Romanesque arch in red sandstone, raised in the reign of the High King Turlough O'Connor - somehow stood. It still stands. Hidden inside a wall for more than five hundred years, then rediscovered, then incorporated into the third cathedral on the site, it remains the oldest part of St Mary's: a stone hinge holding nine centuries of Irish religious history in place.
