Parco Aldo Aniasi, Urban park in Trenno district, Milan, Italy

Parco Aldo Aniasi is a large green space in the Trenno district featuring meadows, woodlands, and a network of wide pathways for walking and movement. Broad tree-lined avenues run through the grounds, creating natural routes that visitors follow for recreation and exercise.

The land was a Scheibler property, used as a military airfield in the First World War: the 74th Squadriglia was based there from 24 November 1916, becoming the 122nd on 12 September 1917 and staying until 30 November 1918, alongside the 108th and 109th. It was farmed until the 1970s, and the park was laid out in 1971. In 2012 it was named after Aldo Aniasi, mayor of Milan from 1967 to 1976.

The park's name honours Aldo Aniasi, Milan's mayor from 1967 to 1976, and it was renamed for him in 2012 after being called Parco di Trenno. Two old farmsteads, the Cassinetta di Trenno to the north and Cascina Bellaria to the south, stood within today's perimeter and were worked until just before the park opened in 1971.

The park lies on Milan's north-western edge, between Municipio 7 and Municipio 8, next to the Trenno district and the San Siro and La Maura racecourses. Long straight avenues can be covered on foot or by bike, and a hedge along the whole eastern side separates the grounds from the racecourse training tracks, which are visible from inside the park.

Double rows of trees line the main avenues, creating natural corridors that harbor diverse wildlife throughout the grounds. This arrangement has gradually developed into an important local ecosystem within the urban setting.
