Before the advent of radio astronomy only two SNRs were known, the Crab Nebulaand Kepler?s. Radio observations played a crucial role in the discovery andinvestigation of SNRs and their environs, revolutionizing the knowledge in the field. Almost seven decades after the first detection of the radio emission coming from SNRs, great advances in the knowledge of their properties have been achieved. Detailed studies of the radio emission associated with SNRs have proven to be an excellent tool to recognize morphological characteristics, to delineate the location of shock fronts, to identify sites of interaction with dense clouds of the ISM, to locate places of particle acceleration, and to discover new PWNe. . They are also powerful probes of the magnetic field, providing information on the orientation and sites of higher compression. I will review the present knowledge of different important aspects of radio remnants, specially focusing on sources of the Milky Way and the Magellanic Clouds, where the radio remnants can be spatially resolved.
