Starting from Alte Brücke, when you see the statues of the Elector and Athena, you are entering the city. Keep walking, and you will reach the steep section of the Philosophenweg. Why is this approximately two-kilometer-long path called the "Philosopher's Path"?
On my first visit to Germany, I was fortunate to attend the 13th edition of Documenta, a once-in-five-years event held in Kassel. Various art pieces and related activities were scattered throughout Kassel, which was incredibly refreshing for me!
