We present MERLlN observations at 73, 18 and 6 cm of the quasar 3C395 (1901 + 319) which has a superluminal component moving towards a stationary knot located at a distance of 15.8 mas from the VLBI core. The observations help to clarify the radio structure of 3C395 on scales ranging from a few tens to a few hundreds of milliarcsec. They show evidence of a highly curved jet-like structure extending beyond the stationary VLBI component. The radio images of 3C395 are consistent with a two-sided structure inclined at a small angle to the line-of-sight, with the approaching jet being decelerated and distorted within ~15 mas of the nucleus. The approaching emission appears to be on the same side as the receding one at distances >~ few hundred milliarcsec from the nucleus, largely due to projection effects. We suggest that the large superluminal speed of 3C395 compared to sources of similar core prominence is due to bends in the jet in the vicinity of the nucleus.
