What to see in Cologne: the highlights
Cologne Cathedral
Begun in 1248 and finished in 1880, after more than six centuries of work, the cathedral was completed faithfully to the original plans. Its north tower reaches 157 m (515 ft): it was the tallest building in the world from 1880 to 1884. It houses the Shrine of the Three Kings, whose relics are said to have been brought to Cologne in 1164. UNESCO added it to the World Heritage list in 1996. The brave climb the 533 steps of the tower; check the opening times, as the cathedral remains a place of worship.
Hohenzollern Bridge and the banks of the Rhine
Just behind the cathedral, Hohenzollern Bridge is the busiest railway bridge in Germany. Cross it on foot to reach the right bank (Deutz), where the view of the cathedral and the old town is at its clearest, especially at the end of the day.
The old town (Altstadt)
Between the cathedral and the Rhine, the old town is a string of squares, lanes and riverside houses. This is where the brewpubs serving Kölsch are concentrated: a light pale beer served in narrow 20 cl (about 7 fl oz) glasses, sometimes 30 cl. The word also refers to the local dialect, spoken by about 250,000 people.
The twelve Romanesque churches
Cologne has a series of twelve large Romanesque basilicas in the Rhenish style, built between the 10th and 13th centuries, most of them outside the old Roman walls. They make a walking route for anyone interested in medieval architecture, alongside the cathedral.
The museums
The Romano-Germanic Museum presents the art and architecture of ancient Cologne. Museum Ludwig holds one of Europe’s leading collections of modern art, including a major Picasso collection. The Roonstrasse synagogue and its museum trace the long history of the city’s Jews. A good option for grey days, which are frequent in winter.
Carnival and the Christmas markets
The carnival season officially opens on 11 November at 11:11 am and runs until Ash Wednesday; its high point is Rose Monday (Rosenmontag), whose date depends on Easter. At the end of the year, Cologne’s Christmas markets attract about 4 million visitors. Book early for both periods.
