St Woolo's Cathedral is a cathedral in Newport, Monmouthshire, Wales. As well as a cathedral, it serves as a parish church.
The name "Woolo" is a corruption of Gwynllyw, the 5th century Welsh saint who first founded a religious establishment on the site.
The present building has sections that date from pre-Norman times, but has been partially rebuilt or extended in every period up to the 1960s.
