The Museum is located in the wing originally used for the workshops and dormitories of the Stelline orphanage. The building was let to private citizens because of the needfor lodgings after the bombings in 1943 which destroyed the building of San Pietro in Gessate. In 2009, l’Azienda di Servizi alla Persona Istituti Milanesi Martinitt e Stelline and Pio Albergo Trivulzio decided to use the building as a showcase fortheir artistic and historical heritage, with the official opening of the Martinitt e Stelline Museum: this is a historical museum whose cultural heritage is displayed through the use of multimedia systems that provide excellent interaction witharchival sources.
