Cologne Cathedral

Christians have worshipped on this site since the 4th century. The current cathedral began construction in 1248, immediately after the relics of the Three Kings arrived from Milan in 1164. Six centuries of building, interrupted by religious wars and revolution, finally concluded in 1880 when the twin spires were completed—briefly making Cologne Cathedral the world's tallest structure.

The relics of the Three Wise Men traveled a long path to Cologne. According to tradition, Empress Helena—Constantine's mother—brought them first to Constantinople. In 314, Constantine entrusted them to Eustorgius I, Bishop of Milan, who transported them by oxcart across the Alps. For eight centuries, the relics remained in Milan.

In 1164, Holy Roman Emperor Frederick Barbarossa conquered Milan. As reward for political support, he gave the relics to Rainald of Dassel, Archbishop of Cologne. Rainald brought them north, and Cologne transformed immediately from regional city to international pilgrimage center. The Magi were understood as 'the first pilgrims'—the first Gentiles to worship Christ. To possess their relics was to possess the very origin of pilgrimage itself.

The existing Romanesque cathedral proved insufficient for this treasure. In 1248, fire destroyed much of the old building, and construction began on a new Gothic cathedral scaled to match the significance of what it would contain. Master Gerhard designed a structure based on Amiens Cathedral but larger, more ambitious—a reliquary the size of a city block.

Construction proceeded for three centuries before halting around 1560. The south tower stood incomplete at 59 meters, a crane atop it that would remain for 300 years. Religious wars, shifting priorities, and changing tastes all played roles. The incomplete cathedral became a symbol of abandoned ambition.

The Gothic Revival of the early 19th century brought renewed interest. Original medieval drawings were rediscovered, and advocates including Sulpiz Boisserée championed completion. In 1842, King Frederick William IV of Prussia laid a new cornerstone. Using the 1300 plans faithfully, architects Ernst Friedrich Zwirner and Richard Voigtel raised the towers to their full 157-meter height. On August 14, 1880, the cathedral was completed—632 years after construction began.
