Founded in 960, Westminster Abbey is one of the world's greatest churches. Site of the coronation of the British Monarchs since 1066, the church also witnessed the marriage of Queen Elisabeth to Prince Phillip in 1947 and Prince William to Kate Middleton in 2011. Explore the Abbey Gardens and Treasures, which include neatly landscaped orchards, cloisters, the Poet's Corner (a burial place for writers, playwrights and poets), the octagonal Chapter House (built in a breathtaking Geometrical Gothic style), 450 tombs and monuments and a museum in the 11th-century vaulted undercroft beneath the former monks' dormitory.
