When was that? I distinctly remember the Ulm cathedral tower stairs in late 1970s to have a dangerous spot with missing railings on either side of narrow and worn brick stairs running along a pane-less window, truly for believers only, and outright unthinkable by today's standards for public trespassing areas. Going all the way to the top of eg Freiburg Münschter also has a thrill to it for those scared of height.
