Cologne Cathedral, High Cathedral of Saint Peter, is a Roman Catholic cathedral in Cologne, Germany. It is the seat of the Archbishop of Cologne and of the administration of the Archdiocese of Cologne. It is a renowned monument of German Catholicism and Gothic architecture and was declared a World Heritage Site in 1996. It is Germany’s most visited landmark, attracting an average of 20,000 people a day and currently the tallest twin-spired church at 157 m height.
The design of Cologne Cathedral was based quite closely on that of Amiens Cathedral in terms of ground plan, style and the width to height proportion of the central nave. The plan is in the shape of a Latin Cross, as is usual with Gothic cathedrals. It has two aisles on either side, which help to support one of the very highest Gothic vaults in the world, being nearly as tall as that of the Beauvais Cathedral, much of which collapsed. Externally the outward thrust of the vault is taken up by flying buttresses in the French manner. The eastern end has a single ambulatory, the second aisle resolving into a chevet of seven radiating chapels.
