Inside a 16th-century Olivetan monastery near the Navigli, Italy's largest science and technology museum spans 50,000 square meters of galleries covering everything from Leonardo da Vinci's engineering designs to nuclear physics. The Leonardo Gallery has the world's largest collection of models built from his drawings — flying machines, hydraulic systems, war machines, textile looms, all constructed at full scale. Outside: the submarine Enrico Toti (Italy's first post-war sub, you climb inside), vintage steam locomotives, a sailing ship fragment, and a Riva motor yacht. The interactive labs make this the best family museum in Milan. Milan guide →
Plan my Milan trip →Leonardo da Vinci Gallery: 130+ models and reconstructions from Leonardo's Codex Atlanticus drawings — the aerial screw (proto-helicopter), the self-propelled cart (proto-automobile), bridges, diving equipment, textile machines. Original manuscript pages are displayed alongside the models. Submarine S-506 Enrico Toti: Guided tour inside the submarine (€10 supplement, book ahead). You walk through the torpedo room, engine room, and command center — claustrophobic, fascinating. Railway Pavilion: A hangar of historic locomotives and carriages — including the 1906 tram that ran Milan's first electric line. Space section: A fragment of moon rock (Apollo 17), satellite models, ISS experiments. Interactive labs (i.lab): Hands-on workshops for kids and adults — robotics, genetics, food science, energy.
