The strikingly anisotropic large-scale distribution of matter, the so-called cosmic web, is made of an extended network of voids delimited by sheets, themselves segmented by high-density filaments, within which matter flows towards compact nodes where they intersect. Do the properties of galaxies, such as their mass, star formation rate or morphology,  retain a memory of these large-scale cosmic flows from which they emerge? And what are the signatures of this environment at different locations within the cosmic web? In this talk, I will address these questions using the set of observed and virtual galaxies, from the spectroscopic surveys and large-scale hydrodynamical simulations, emphasising the existing challenges both on the side of theory and observations and presenting future perspectives from ongoing and upcoming surveys.
