The UNESCO World Heritage Site in Germany containing Cologne Cathedral is Cologne Cathedral.
Cologne Cathedral is a monumental Gothic church on the Rhine in Cologne. Construction began in 1248, but the project was interrupted for centuries and the cathedral was not completed until 1880. Its twin towers rise about 157 metres, making it one of the most prominent landmarks in the city and one of the largest Gothic cathedrals in Europe.
The cathedral is associated with the Shrine of the Three Kings, a richly decorated reliquary traditionally said to contain relics of the Magi. Its design drew on medieval French Gothic architecture, while its completion reflected nineteenth-century enthusiasm for Gothic revival and national heritage. UNESCO inscribed Cologne Cathedral in 1996; the site was briefly placed on the List of World Heritage in Danger in 2004 because of development concerns.
