A striking example of expressionist architecture is located directly on the Rhine in the form of the Bastei, which opened in 1924. Built by architect Wilhelm Riphahn, the restaurant is built on the base of a former Prussian fortress tower and has taken on the name. The architecture, which was modern for its time, was initially controversial when it was built because there were concerns that it would spoil the panoramic view of the Rhine. However, these fears quickly gave way to enthusiasm for the modern building.
For Wilhelm Riphahn, the bastion signalled his professional breakthrough. Later, after the building was destroyed in the Second World War, Riphahn rebuilt it in its original form. With its view over the Rhine, the Bastei was one of the best addresses for events for many years. Unfortunately, however, the listed building showed considerable substantial defects. It has therefore been closed. Whether and how maintenance can be guaranteed is currently being examined.
