Cologne

Cologne Cathedral is one of the greatest Gothic buildings in the world and the most visited landmark in Germany. Its twin spires, reaching 157 metres, dominate the skyline and were the tallest structures on earth when the building was finally completed in 1880.

Construction began on August 15, 1248, and it took 632 years to finish. Work halted in the 1560s due to lack of funds and changing priorities, and the cathedral stood unfinished for three centuries. Construction resumed in 1842 after the original medieval plans were rediscovered, and the building was completed in 1880 in a remarkable act of historical fidelity.

The cathedral was built to house the Shrine of the Three Kings (Dreikonigenschrein), a golden reliquary said to contain the remains of the biblical Magi. The shrine, completed around 1225, is the largest reliquary in Europe and remains the cathedral's greatest treasure.

At 144.5 metres long and 86 metres wide across the transept, it is the largest Gothic church in Northern Europe. Inside, the Gero Crucifix, carved around 970 AD, is the oldest monumental crucifix in the Western world.

During World War II, the cathedral was hit by 14 aerial bombs but remained standing, even as the rest of Cologne was reduced to rubble. Some believe the Allies used the spires as a navigation landmark, which may have spared it from complete destruction.

The cathedral is a UNESCO World Heritage Site (since 1996) and receives around 6 million visitors a year. Entry is free, though tower climbs have a fee.

On a Questo quest through Cologne, the cathedral is impossible to ignore, and its stories go as deep as its foundations.

Discover Alter Markt, Cologne's historic old market square and vibrant heart of the city's medieval Old Town (Altstadt), where centuries of commercial activity, civic governance, and social life have unfolded in community celebration. The square is surrounded by painstakingly restored medieval buildings with steep red roofs and colorful facades transporting visitors directly back to earlier centuries and historical periods. These buildings house restaurants, cafes, and shops where aromas of German cuisine and coffee drift into the square creating irresistible sensory experience and cultural immersion. The Alter Markt serves as gathering place where locals and visitors converge, street musicians perform, and energy of Cologne's community life pulses continuously through every season. In medieval times, the square was Cologne's center of commerce and governance; merchants displayed goods, civic authorities held court, and populations assembled for announcements and celebrations of historical importance. Walking across cobblestones worn smooth by countless feet across centuries connects you to generations of Cologne residents and their daily activities. The Town Hall with its Gothic spire overlooks the square, symbolizing civic authority and architectural ambition of its era in city planning. The square's medieval character remains remarkably preserved despite history's challenges, including World War II bombing and subsequent careful restoration by dedicated citizens. Traditional German pubs and restaurants serve authentic local cuisine and beverages, continuing hospitality traditions spanning centuries. With Questo, you can explore Cologne's Old Town and discover stories of merchants and citizens.
