Cologne Cathedral is Germany’s most-visited landmark and one of the greatest achievements of Gothic architecture in the world. Construction began in 1248 and was not completed until 1880 — a gap of 632 years — making it one of the longest building projects in history. When the twin spires were finally completed, at 157 metres, it was briefly the world’s tallest building. UNESCO inscribed it as a World Heritage Site in 1996.
The Shrine of the Three Kings
The cathedral’s most sacred treasure is the Shrine of the Three Kings — a gilded reliquary containing the relics believed to be those of the Biblical Magi: Caspar, Melchior and Balthasar. The relics were brought from Milan by Emperor Frederick Barbarossa in 1164, and the Cologne Cathedral was built, over six centuries, to house them. The shrine is the most important reliquary in the Western church and made Cologne one of the great pilgrimage destinations of medieval Europe.
Survival in War
In the Second World War, Cologne was bombed 262 times and the city was devastated. The cathedral sustained 14 direct hits but, unlike the city around it, was never structurally destroyed — it stood as a single remaining landmark in a field of rubble, visible from Allied bombers as a navigation point. Locals say it was spared by Providence; others note that the Allies preserved it deliberately as a navigation aid. Either way, it survived — and continues to receive 6.6 million visitors per year.
