Results of a program to investigate the kiloparsec-sized radio structure of a representative sample of Compact Steep Spectrum (CSS) sources from the 3CR catalog (Jenkins et al., 1977) are presented. Ten objects (3C49,67, 119, 237, 241, 268.3, 287, 303.1, 343, 343.1) have been mapped at 18 cm with a resolution of about 30 marcsec using the European VLBI Network. In some cases the VLBI data have been supplemented by MERLIN observations at the same wavelength to enhance sensitivity to large-scale structure. The overall sizes of the CSS sources range from about 0.1 to 1 or 2 arcsec, corresponding to linear sizes of the order of 1 to 10 kpc. The morphological classification ranges from double to core-jet to complex; CSS quasars are generally core-jets or complex, while CSS radio galaxies are doubles, although not necessarily simple doubles.
