The Ulrico Hoepli Planetarium has been in existence since 1930, and is located within the Indro Montanelli public gardens on Corso Venezia in Milan, Italy. Ulrico Hoepli Planetarium is the largest planetarium in all of Italy, and one of the largest in Europe as well. The planetarium itself is named for Ulrico Hoepli, a Swiss national who moved to Milan in the late 1800s and was responsible for the first libraries to open to the public in the city, but it was actually built by Piero Portaluppi and donated to the city. The Ulrico Hoepli Planetarium is located in northeastern Milan, and is accessible via public transportation. The Ulrico Hoepli Planetarium consists of a huge projection hall with an immense dome overhead, and seats upwards of 600 people. Scientific lectures are often conducted there, and guided tours are available. The Ulrico Hoepli Planetarium is a popular family attraction, so give yourself plenty of time if you want to see a presentation. Ulrico Hoepli Planetarium is open only on weekdays, and there is a fee for admission. Usually the presentation changes every month, to cover the sky for an entire year, and special events are planned from time to time with children in mind, including presentations accompanied by music, or storytelling. All presentations are in Italian.
