From Berlin, we headed to Paris, visiting the central municipality. The mayor there was very approachable and treated us with great respect. He was a significant figure who later became the President. During our meeting, we engaged in a Q&A session, where everyone asked questions based on their understanding and knowledge. Initially, I asked him to explain some of the methods used for collecting fees in Paris. He mentioned, “For example, if a shopkeeper on the street wants to put up a sale advertisement behind the shop window, they must pay twenty-five francs.” This amount seemed quite high to me, indicating that the city charges substantial fees. I then inquired, “What’s the biggest challenge you face with the citizens?” After some thought, he replied, “Our biggest challenge is preserving the city’s architecture. Most buildings in our city are old, and we strive to maintain this historical architecture. However, large companies come in, buy a neighborhood or block, and then request to rebuild; we do not permit this, but they apply pressure from various sources like newspapers, creating conflicts. Maintaining the old city architecture and dealing with large-scale construction is our most significant issue.”
