The planetarium permits observation of the stars of the sky thanks to the projections onto the dome screen and seasonal positions of the stars. The building was designed by Architect Portaluppi and situated within the Public Gardens of Palestro by request of the Editor Hoepli who then donated it to the city in 1930.
Projection shows and conferences are organised throughout the year. Ring in the morning to book your visit as opening times vary depending on what events are on. There are special opening times for schools.
