Powerful radio galaxies often display regions of enhanced optical/UV emission, elongated and aligned with the radio jet axis. The expanding radio source strongly affects the surrounding IGM, and the properties of the aligned emission regions vary considerably with both radio source properties and cosmic epoch. The results of deep rest-frame UV and optical imaging of high redshift 6C radio galaxies are discussed, considering the influence of radio power on the strength of the observed alignment effect, the galaxy colors and the dominant emission mechanisms.
