Monte Stella, also informally called Montagnetta di San Siro is an artificial hill and surrounding city park in Milan, Italy. The park, established in the 1950s, has an overall area of 370,000 m². 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.
The park is located in the QT8 district. This was an experimental district that was completely designed after the World War. The hill itself was designed by architect Piero Bottoni, who led the team of architects who contributed to the QT8 project. Bottoni dedicated the hill to his wife, Stella.
