The role played by the large-scale environment on the nuclear activity ofradio galaxies (RGs), is still not completely understood. Accretion mode, jetpower and galaxy evolution are connected with their large-scale environmentfrom tens to hundreds of kpc. Here we present a detailed, statistical, analysisof the large-scale environment for two samples of RGs up to redshifts$z_\mathrm{src}$=0.15. The main advantages of our study, with respect to thosealready present in the literature, are due to the extremely homogeneousselection criteria of catalogs adopted to perform our investigation. This isalso coupled with the use of several clustering algorithms. We performed adirect search of galaxy-rich environments around RGs using them as beacon. Toperform this study we also developed a new method that does not appear tosuffer by a strong $z_\mathrm{src}$ dependence as other algorithms. We concludethat, despite their radio morphological (FR\,I $vs$ FR\,II) and/or theiroptical (HERG $vs$ LERG) classification, RGs in the local Universe tend to livein galaxy-rich large-scale environments having similar characteristics andrichness. We highlight that the fraction of FR\,Is-LERG, inhabiting galaxy richenvironments, appears larger than that of FR\,IIs-LERG. We also found that 5out of 7 FR\,II-HERGs, with $z_\mathrm{src}\leq$0.11, lie in groups/clusters ofgalaxies. However, we recognize that, despite the high level of completeness ofour catalogs, when restricting to the local Universe, the low number of HERGs($\sim$10\% of the total FR\,IIs investigated) prevent us to make a strongstatistical conclusion about this source class.

Deciphering the large-scale environment of radio galaxies in the local Universe: where do they born, grow and die?
