Thanks to excellent sensitivity and wide field-of-view, the Fermi-LAT enables for the first time a non-bias survey of blazars even in their quiescent state. Simultaneous monitoring of the optical polarization also provides brand-new knowledge on internal structure and particle acceleration in the jet. The gamma-ray emission from about 10 radio galaxies have been discovered to date, providing new challenges to the unification theory of the AGN. Detection of gamma-ray emission from giant radio lobes in Centaurus A may suggest a possible association with the highest energy cosmic-ray and importance of turbulent acceleration in the intergalactic space. 103 8 493
