On a sunny fall day, Karina Rohlfing took a group of new CDTF students on a tour of Paderborn incl. a quiz, showing them beautiful places and cultural peculiarities in the city center. With the help of a model of the city center, located at the Kamp, she explained that Paderborn, like other European cities, was protected against invaders by a city wall. Next, the group walked by the historic city hall to the springs of the Pader. Approximately 5,000 liters of water per second get to the surface in the spring basins in the park. Even today, a grain mill is run by the water of Germany’s shortest river; the undershot mill wheel of Stümpel’s mill generates electricity. At the Dom (cathedral), the students looked at the perspective grid and other things. An anecdote has it that if you touch the peacock’s head on top of the well near the Three-Hares window – as shown in the photo – you will experience something special.
