How can you develop a bridgehead with a small customs house and a restaurant? The potential lies in the existing landscape elements. Overgrown retaining walls and old trees characterize the island of "Burg Stein" and the bank area of ​​the customs property. The tree population is rounded off here to form a small park, the castle island and new customs link the two ends of the bridge as a pair to form an ensemble. Both parks have their own character and are an indispensable part of building bridges.
