Durham Cathedral is lauded as the greatest Norman building in England, perhaps even in Europe. It is cherished not only for its architecture but also for its incomparable setting on high and above the river. For this reason it was listed, together with the Castle, as one of Britain's first World Heritage Sites. In a nationwide BBC poll held in 2001 it was voted the nation's best-loved building. Just like Hadrian's Wall and the Angel of the North, it is an icon of the north-east of England, its image is instantly recognisable to people who love this part of Britain.
