Sforza Castle was built in the 5th century under the orders of the then ruler Sforza. It is still very well preserved and has been a prison in history. The rooms in the castle are now built into museums, including the Museum of Applied Art and Music, the Museum of Archaeology and the Museum of Ancient Art. On the second floor, there are galleries, musical instruments and an archaeological museum displaying Egyptian relics. Now the castle is also a scenic tourist attraction. Among the many castles in Europe, Castello Sforzesco is not gorgeous, let alone stunning, but it witnesses the history of Milan. Its existence is like a Book telling the story of Milan. On this day, I went into Sforza Castle, looking for the glory and decline of Milan. It takes less than 20 minutes to walk from Milan Cathedral to Sforza Castle. The castle looked bleak in the gloomy weather. Although it was not as gorgeous as a cathedral, it could hardly see the scale and spirit of the castle. The central tower of the castle stands tall and recognizable from a long distance. It is said that at night there are sometimes charming lights. There was a pool in front of the castle, and the spring was leaping with agility.
