The park area was formed at the end of the 19th century after the construction of the Arch of Peace. Its construction began in honor of Napoleon, but the theme was changed due to his defeat. The arch was located near the Sforza Castle. Initially, there was a plan to develop a residential quarter between them, but it was eventually decided to create a public park. The work was carried out from 1890 to 1893 under the project of the Italian architect Emilio Alemagna. This site had been used as a training ground for a long period.
The park was laid out according to the romantic example of English counterparts. It included wide avenues, which allowed for carriage rides, a pond, and a belvedere. Numerous exhibitions were held here, including the United Expositions in 1894 and the international exhibition Exposition in 1906. The Palazzo dell'Arte still hosts the Milan Triennale to this day.
The green zone covers 50 hectares and is designed in the English style. In the center, there's an artificial lake inhabited by ducks and turtles. Nearby is the Little Mermaids Bridge – the first such cast-iron structure in Italy, erected earlier in 1842. The entire area is planted with shrubs, trees, and flower beds. Between them, pedestrian paths and lawns have been laid out, where one can have a picnic. Sports grounds are also established. In this place, one can encounter unusual inhabitants – colorful parrots. In addition to two main attractions, the Arch of Peace and Sforza Castle, there are other features on the territory.
The Palazzo del Arte is located in the central part of the park, built in 1933. Its interior has been redesigned according to the latest interior trends. It hosts exhibitions of contemporary art and cultural events. There's also its own collection in the Design Museum.
This metal tower serves as an observation deck, 108.6 meters high. It is positioned so that it offers a view of the entire historic city and some of the surrounding areas. An elevator lifts visitors to the top.
The building was erected in 1906 for the opening of a scientific exhibition. Then, for some time, it was vacant until an aquarium and a hydrology department were opened here. The tour takes place in tunnels with transparent walls and ceilings, through which fish from the Mediterranean Sea and European rivers swim.
After the Triennale, unusual art objects remained in the park: the Library Pavilion, Bar Bianco with a large terrace overlooking the park, Continuo Street Theatre, Mini-amphitheater Accumolazione Musicale e Seduta, and the "Bagni Misteriosi" fountain by Giorgio de Chirico.
