Mrk 1498 is part of a sample of galaxies with extended emission line regions(extended outwards up to a distance of $\sim$7 kpc) suggested to bephoto-ionized by an AGN that has faded away or that is still active but heavilyabsorbed. Interestingly, the nucleus of Mrk 1498 is at the center of two giantradio lobes with a projected linear size of 1.1 Mpc. Our multi-wavelengthanalysis reveals a complex nuclear structure, with a young radio source(Giga-hertz Peaked Spectrum) surrounded by a strong X-ray nuclear absorption, amid-infrared spectrum that is dominated by the torus emission, plus acircum-nuclear extended emission in the [OIII] image (with radius of $\sim$ 1kpc), most likely related to the ionization of the AGN, aligned with the smalland large scale radio jet and extended also at X-rays. In addition alarge-scale extended emission (up to $\sim$ 10 kpc) is only visible in [OIII].These data show conclusive evidence of a heavily absorbed nucleus and hasrecently restarted its nuclear activity. To explain its complexity, we proposethat Mrk 1498 is the result of a merging event or secular processes, such as aminor interaction, that has triggered the nuclear activity and produced tidalstreams. The large-scale extended emission that gives place to the actualmorphology could either be explained by star formation or outflowing materialfrom the AGN.
