A 1.5 Mpc radio galaxy has been discovered at a redshift 0.206. Using maps at three frequencies we estimate a source age ~7.5x10^7^yrs, an expansion speed ~0.03c, a jet power ~10^44^erg/s and an external density <=10^-6^cm^-3^. We conclude that the source has a large size because it has expanded in a low-density ambient medium and not because it is very old.
