Cologne Cathedral, Roman Catholic cathedral church, located in the city of Cologne, Germany. It is the largest Gothic church in northern Europe and features immense twin towers that stand 515 feet (157 metres) tall.

The famous church is the Cologne Cathedral (Hohe Domkirche Sankt Petrus), a masterpiece of High Gothic architecture and a UNESCO World Heritage site. Construction began in 1248 but took a staggering 632 years to complete, finally finishing in 1880. It is the most visited landmark in Germany in 2026, attracting over 20,000 people daily. The Cathedral is renowned for its twin spires, which stand 157 meters (515 feet) tall, making it the tallest twin-spired church in the world. Inside, its most precious treasure is the Shrine of the Three Kings, a gold sarcophagus believed to hold the remains of the Biblical Magi. In 2026, the Cathedral is still a place of active worship and a "perpetual construction site," as the specialized sandstone requires constant restoration due to centuries of weathering and the "blackening" caused by industrial-era pollution.
