Durham Cathedral is the greatest Norman building in England, perhaps even in Europe. It is cherished not only for its architecture but also for its incomparable setting. For this reason it was inscribed 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. Like Hadrian's Wall and the Angel of the North, it is an icon of north-east England, its image is instantly recognisable to people who love this part of Britain.
