Kreuzbergkirche sits above Bonn on the Kreuzberg, giving the city a pilgrimage church with both architectural and landscape appeal. The church is especially known for its Holy Stairs, a devotional feature modelled on Rome’s Scala Santa tradition.
It is a little outside the central museum-and-Beethoven circuit, which is part of the reason to go. The visit works best for travellers interested in religious architecture, quiet viewpoints, and the older spiritual geography around Bonn.
