On the southern bank of the Waal River lies the city of Nijmegen, a major industrial center where brick manufacturing, the chemical industry, tobacco production, and electrical equipment manufacturing are especially well developed. One of the most curious constructions, shaped like a whale, is located on the Waal's riverbank — it’s the river fleet control center, as Nijmegen also serves as a river port. Nearby stands a sculpture of the fictional heroine Mariken van Nijmegen, who has become a symbolic figure for the city.

Nijmegen is also home to the fascinating National Bicycle Museum “Velorama.” Interestingly, it is the only museum of its kind in the Netherlands, despite the country’s well-known love of cycling. The museum’s exhibitions display the beauty and diversity of bicycle transport. Today, its collection includes over 500 bicycles.
