ABSTRACT=We present the analysis of near-infrared Hubble Space Telescope imaging of 10 Fanaroff  Riley II powerful radio galaxies at low redshift (0.03<z<0.11) optically classified as narrow-line radio galaxies. The photometric properties of the host galaxy are measured using Galfit, and compered with those from the literature. Our high resolution near-infrared observations provide new and direct information on the central kpc-scale dust lanes in our sample that could  be connected to the pc-scale torus structure. Moreover,  analyzing the infrared spectrograph Spitzer spectra of our sample,  we suggest  properties of the dust size of the torus}.
