Located at the foot of the southwestern Alps in Bavaria, Germany, the town of Fisen, at the border between Germany and Austria, is comfortable and simple. The deep alleys witness the prosperity of the Middle Ages, with Gothic spires towering over the clouds. At the ruins of the ancient city wall, the churches with different decoration styles during the Baroque and Rococo periods are scattered, and the clear and pure Laixi River flows. The beauty of the fairy tale world is like this.
