Abstract: 
We report on centimeter VLA and VLBI observations of the giant, low power radio galaxy 1144+35. On the parsec scale, we see a complex jet component moving away from the center of activity at 2.7h <SUB>50</SUB><SUP>-1</SUP> c . We detect a faint parsec-scale counter-jet and derive a jet velocity of 0.95 c and an angle to the line of sight of 25°, consistent with an intrinsically symmetric ejection. These findings lend credence to the claim that even the jets of low-power radio galaxies start out relativistically.
