With a foreword by Gerhard Richter, recorded by Joachim Frank. Why is the Gymnasium on Kreuzgasse so characteristic of the 1950s and worthy of preservation? What makes Wilhelm Riphahn's ensemble of buildings on Hahnenstrasse a distorted beauty? And why is the late Gothic Annunciation group of the Romanesque church of St. Kunibert particularly worth seeing? The former Cologne cathedral master builder, Barbara Schock-Werner, has co-authored a guide to Cologne with journalist Joachim Frank, based on her successful column in the Kölner Stadt-Anzeiger, which leads to hidden gems as well as to eyesores. "This book should be like my tours in the cathedral, after which people often say: We've been here so many times, but what you showed us, we've never noticed before." Barbara Schock-Werner.
