  We present images showing the first detections of polarization on parsec
scales in the nuclei of four Fanaroff-Riley type I (low-luminosity) radio
galaxies. Observations with Very Long Baseline Interferometry at \lambda 3.6cm
reveal the presence of ordered magnetic fields within ~1650 Schwarzchild radii
of the putative central supermassive black hole. The relatively high fractional
polarization in the pc-scale jets of these galaxies is consistent with the
standard scheme unifying low-luminosity radio galaxies with BL Lac objects.
This result also suggests that these radio galaxies lack the obscuring tori
that apparently depolarize the nuclear emission in the more powerful FRII radio
galaxies, and that their supermassive blackholes are poorly fed and/or
inefficient radiators.
