Monte Stella ("Starmount"), also informally called Montagnetta di San Siro ("Little mountain of San Siro") is an artificial hill and surrounding city park in Milan, Italy.
The hill was created using the debris from the buildings that were bombed during World War II, as well as from the last remnants of the Spanish walls of the city, demolished in the mid 20th century.
Even at only 25 m height, the hill provides a panoramic view of the city and hinterland, and in a clear day, the Alps and Apennines can be distinguished from atop.
A notable area of the park is called "Giardino dei Giusti" (Garden of the Just), which is a memorial to distinguished opponents of genocide and crimes against humanity; each tree in the garden is dedicated to one such person.
Notable people who have been dedicated a tree in the Giardino dei Giusti include Moshe Bejski, Andrej Sakharov, Svetlana Broz, and Pietro Kuciukian.
