Young radio sources are downscaled versions of the large, extended radio galaxies. The former are smaller than ~20 kpc, being embedded in the ISM of their host galaxy, while the latter can reach a few Mpc in size. To date only the most powerful objects have been studied and therefore current understanding refers to the most luminous objects. A brief review of the properties of the young radio sources (mainly radio, given their lack of outstanding phenomena in other observing windows) will be given, along with a schematic interpretation as early stage in radio source evolution.
