Because most stars carry in their outer envelopes the chemical composition inhered at birth, it should be possible to map the star formation history in different parts of the Milky Way by measuring, for stars of different ages, a large array of chemical elements covering different nucleosynthetic sites. This goal seems to be still reachable even in the presence of mergers and radial stellar mixing, i.e., the fact that stars can move away from their birth places, loosing most of their kinematical memory. In particular we will highlight recent results obtained from the combination of asteroseismology, Gaia, photometric and spectroscopic surveys. The new data can take us out from the very local volume, enabling finally a more holistic view of our Galaxy. We close by discussing where more data is needed and the future plans of 4MOST.
