The Ministry of the Navy presented an exhibition divided into five sections, one for each of the rooms in the pavilion assigned to it: models, weapons and machines, the Istituto Idrografico di Genova [Genoa Hydrographic Office], the Ufficio Tecnico Fari di La Spezia [La Spezia Lighthouses Technical Office], and radiogram apparatuses. Most of the material displayed came from the Arsenal of La Spezia.
