The cathedral was designed by Quinlan Terry. Architecturally the inspiration is early Italian Renaissance crossed with the English Baroque of Christopher Wren. The windows have characteristically English lead cames fixed to bronze saddle bars with small panes. The clerestory is faced in Smeed Dean stock brickwork and the roof is Welsh slate. All 5 orders have been employed in the design; Tuscan for the arcade, Doric for the main giant Order, Ionic for the east and west Serlian windows, Composite and Corinthian for the organ and cathedral. Stations of the Cross were sculpted by Maklouf.
