The Domus Mazziniana comprises a museum, through which one can follow the life of Mazzini and the key moments of the Risorgimento with letters, documents and photographs of the time. The exhibition is divided on two floors: on the ground floor, Mazzini's youth is retraced along with the protagonists of the time through objects and graphic installations. On the upper floor, the fundamental moments of Mazzini's adventure are narrated through multimedia content. From here, one can access the room where Giuseppe Mazzini passed away, where the only existing signed copy of the "Giuramento della Giovine Italia" can be found.
Mazzini's completeworks are collected in the library and archive, along with many of his manuscripts and about twenty newspaper articles of various origins, adding up to a total of about 87,000 original documents.
