The wall of Rothenburg, the romantic road, has a path built by the Rothenburg Wall, which surrounds the entire castle. Today, this plank road has become the best walking route to see the entire ancient city. This complete wall surrounding the town is 3.5 km long, of which 2.5 km is open to visitors. There are also various gates and towers between the walls of the city, including the oldest white gate of the North Gate, Marcus Tower on the arch, and the hospital gate with fortifications on the south. Heber next to the most beautiful street corner Simmen, the castle gate leading to the castle garden, and so on, all have their own characteristics. Looking at the ancient city of Rothenburg from another angle is another feeling. We climbed the city wall from the door of the hotel, such as the Rhodes Gate, and began to travel around the ancient city wall until we could not go any further. Later, I realized that the 2.5 kilometers that were open to tourists were not continuous. We took the experience of the Rhodes Gate and thought it was a classic one. The ancient city walls of Europe are very different in appearance from the ancient Chinese city walls, but the function is to defend against foreign enemies and guard their own homes. This ancient Chinese and foreign thoughts are surprisingly consistent. Wooden fences, raised stone walls, and even the ground are uneven, all indicating the traces of the years, revealing the vicissitudes of thousands of sails. Compared to the colorful fairytale cottages in the ancient city, it is not romantic, but it is a good place to care for the past. Many people on the wall will take this cabin (P9), the classic German-style wooden rib house, the red tile spire, the flower water well, and the romance. With the guidance of the city walls, we gradually moved away from the center, and the whole world was quiet immediately. The city wall was partially damaged in the war and is now being repaired through donations from people around the world. Walking through the city walls, you can see the names of many donors engraved on them, many of them are in the country, the most of which are Japanese. Many Japanese who came to Germany for help later stayed in Germany and stayed in Rothenburg. This is also the reason why there are quite a few Japanese restaurants in Rothenburg.
