St Albans Cathedral, formally the Cathedral and Abbey Church of St Alban, and referred to locally as "the Abbey", is a Church of England cathedral in St Albans, England. Much of its architecture dates from Norman times. It ceased to be an abbey in the 16th century and became a cathedral in 1877. Although legally a cathedral church, it differs in certain particulars from most other cathedrals in England: it is also used as a parish church, of which the dean is rector with the same powers, responsibilities and duties as that of any other parish.
Probably founded in the 8th century, the present building is Norman or Romanesque architecture of the 11th century, with Gothic and 19th-century additions.
