We present results from global VLBI, VLBA, MERLIN and VLA observations of the quasar 3C 395 at 5.0GHz, global VLBI and VLBA observations at 8.4GHz, and VLBI test observations at 22.2GHz. These combinations allow us to obtain radio images with resolutions ranging from 0.2 to 200 milliarcseconds, which show the continuity of the radio structure of 3C 395 from parsec to kiloparsec scales. On parsec scales we find clear signs of activity in the compact core and show that the component separations have remained unchanged since epoch 1990.8. On larger scales we confirm the existence of a very sharp bend in the jet at a distance of ~70mas from the core, the magnitude of which we ascribe to projection effects when the jet is viewed very close to the line of sight. We suggest that 3C 395 is a double radio source viewed end-on, with two extended lobes appearing superimposed as a low brightness halo.
