Going to Shanghai Fort Debao, you can see the entire Heidelberg town. Especially at night, although the town is very quiet, but under the lighting, it is not lonely. The quiet Neckar River, accompanied by an elegant night, is intoxicatingly romantic. The ruins of the most famous Heidelberg castle in the city tower above the old town. The castle has been in existence for more than 400 years and consists of various styles of barriers, outbuildings and palaces from Gothic to the Renaissance. This castle is located in the city's commanding heights and is also a great viewing platform. Standing on the front of the city, the horizon is full of boundless vineyards, beautiful. The big barrel and the large wine cellar that can store 220,000 liters of wine in the fort are the most attractive attractions in Heidelberg. The two main buildings in the east and north of the courtyard are built in the 16th century. Today they are recognized as the most important building in the history of German architecture. The castle is also open at night, and the castle under the night is another scene, which is very different from the day. In the dark night on the top of the mountain, the ancient wall is decorated with lights, giving a mysterious atmosphere, staring at this majestic legendary building, and the thoughts of the past can be seen in my mind. Unconsciously following it, entering the ancient times.
