This is one of the oldest cathedrals in England (its cornerstone was laid in 1080). The cathedral is primarily Norman and includes a 13th-century Lady Chapel, erected in 1220, as well as a majestic "Father" Willis organ, one of the finest in the world.

Exhibited together in the new library building at the west end of the Hereford Cathedral are two of Hereford's unique and priceless historical treasures: the Mappa Mundi of 1290, which portrays the world oriented around Jerusalem, and a 1,600-volume library of chained books, with some volumes dating from the 8th century. The cathedral also contains the Diocesan Treasury and the St. Thomas à Becket Reliquary.
