Aachen Cathedral is one of the oldest and most historically significant churches in Germany — the first German site inscribed as a UNESCO World Heritage Site, in 1978. The Palatine Chapel at its core was built by Emperor Charlemagne in 796–806 AD as his private chapel and court church, making it the oldest cathedral in the German-speaking world still in use. Charlemagne, who united Western Europe under Christian governance, is buried here beneath a gold shrine that is one of the most important reliquaries of the medieval world.
Architecture and Treasures
The cathedral complex has grown around the original octagonal Palatine Chapel across twelve centuries. The Gothic choir, added in the 14th century, contains the Pala d’Oro — a golden altarpiece — and the throne on which all German kings from Charlemagne’s time until 1531 were crowned. The Karlsreliquiar (Charlemagne’s Bust Reliquary, 1349) and the Marienschrein (Shrine of the Virgin, c. 1230) are among the supreme masterpieces of medieval goldsmithing and are displayed in the Domschatzkammer (Cathedral Treasury).
The Septennial Pilgrimage
The Aachen Pilgrimage (Aachener Heiligtumsfahrt) is held every seven years — a septennial event in which four sacred relics associated with Marian and Christological devotion are displayed to pilgrims for ten days. The next pilgrimage is scheduled for 2028. On pilgrimage years, over one million pilgrims visit Aachen from across Europe.
