We report on the properties of low redshift radio galaxies (LzRGs) and their central black hole. We find that LzRGs lie on the same fundamental plane defined by non-active elliptical galaxies. Just representing the brightest and most massive population of early type galaxies. Using the relations between black-hole mass (MBH) and bulge luminosity or stellar velocity dispersion, we infer MBH of LzRGs. These masses are in the range between ~5×107 to ~6×109Msolar and the black-hole mass is proportional to the mass of the host galaxy (MBH~0.001×Mbulge). No significant correlation is found between MBH (or Mbulge) and the radio power at 5 GHz.
