Around 1780, a round room was added in the Louis XVI style. The dome room partially protrudes above the river and became the most beautiful Maas room in Wolwevershaven. To this day, the hall and the view are spectacular. Nowhere else can you see the confluence of the Oude Maas, the Beneden Merwede, and the Noord better than here. It is the busiest three-river junction in Europe.
