This modern building, which blends remarkably well into the cathedral's façade, is home to the treasury. Countless works of art are displayed including fourteen 15C reliquary-busts of the Prophets, the 11C head-reliquary of St Paul and a 13C Virgin - both of them in chased gold - which surround the Processional Cross of the Chapter, the prize possession of the Treasure House. Admire the fine collection of liturgical vestments in the basement.
