A number of analysis techniques use neutrons of different energy/wavelength as a probe to investigate a broad range of ancient metal artifacts and provide valuable information related to provenance, production techniques and conservation status. Some examples from recent studies ranging from architechture to goldsmith are reported. Neutron diffraction and neutron imaging were used for investigating 18 m long iron beams from Milan's Cathedral and probe the bulk of the $8\times 8 cm^{2}$ beam cross section. At the other extreme in size the elemental and isotopic composition of gold filigree fragments from the recently restored Croce di Chiaravalle Milanese were determined with prompt gamma activation analysis.
