In a month's time, it's all or nothing. It's about your promotion at school. You have to present what is sacred to Cologne. 

There is only one chance. Make a pilgrimage through the city from station to station. Solve all the puzzles and discover unique objects, works and brands without which Cologne would be unthinkable. You could also say: all this is sacred to the people of Cologne!

If you now also find out why all this is sacred to the people of Cologne, then your presentation will be a hit. Your transfer is assured.
