The Cathedral of Aix-la-Chapelle
The Church of Charlemagne was in 1978 the first building in Germany to be declared a World Heritage Site, in order to take account of the universal significance of sacred architecture in terms of both architectural and art historical significance.
The cathedral, which is over 1200 years old, is a building consisting of several partial buildings and influenced by many architectural styles.
The foundation stone of the Palatine Chapel was laid around 795 by order of the emperor Charlemagne.
After his dead in 814 the Palatine Chapel was the coronation place of German kings from 936 to 1531.
Today, the Cathedral of Aix-la-Chapelle is the bishop's church of the diocese of Aachen and the city's most important landmark.
