Sempione Park (Parco Sempione) occupies the area between Castello Sforzesco and the Arch of Peace. It one of the most green places in Milan with a lot of trees, meadows and artificial ponds.
Park has been laid out in 1893 in classical English style by architect Emilio Alemagna. Few years ago, it was totally renovated.
Today it’s popular place of relaxation in the city. Also you can find a lot of sports and play grounds in the park. In the summer time, in the Sempione Park are conducting different exhibitions and the concerts.
Park has been built over the place where once stood Spanish Fortress. Almost nothing left from the fortress but you can see the vestiges of the shafts and moats.
Another one sight in the park is a Stadium, which was built in the beginning of 19 century and called “Arena”. When I visited Milan it was closed but hope you will be more lucky.
