3C 236 is a Fanaroff and Riley Class II (FR II) radio galaxy. It is among the largest known radio galaxies, with the radio structure having a total linear size in excess of 4.5 Mpc (15 million light years). The galaxy features a "double-double" radio morphology consisting of the giant relic 4.5 Mpc source and an inner 2 kpc compact steep spectrum radio source. A recent starburst episode near the nucleus may be related to the event resulting in re-ignition of radio activity.^[3]
