The house where the Queen's mother-in-law stayed. A stone man standing in an outrageously indecent pose at the Old Town Hall. The city's wealth hidden in a crypt. The stones of the Old Opera in a new form. A milestone that inspired BAP singer Wolfgang Niedecken to write a song. Cologne is colorful, warm-hearted, contrasting, and vibrant. But a beautiful exterior alone is not enough to captivate for long. It takes more: history, experience, and secrets. And the cathedral city has plenty of those: the patron saint and the Kölsch beer. Unevenly laid stones of a Roman road - a Cologne prank. Behind all this are great stories that journalists Eva-Maria Bast and Manuela Klaas uncovered together. They were supported in their quest by the EXPRESS and the best city experts of all: the people of Cologne. Among them is Konrad Adenauer, grandson of the namesake Chancellor and Cologne's mayor, who shares a moving story about his grandfather. The result is a refreshingly different perspective on this vibrant city on the Rhine. You will be surprised by the secrets that lie dormant in this city.
