Compelling evidences for oscillactions of solar and atmospheric neutrinos have been acumulated over the last years[1]. The neutrino oscillations have been also confirmed with artificially produced neutrinos. The neutrino oscillations imply the existence of 3-neutrino mixing in vacuum. This vast experimental program has proven the oscillation between sets of two neutrino flavours. The existence of a third mixing angle, the Dirac or Majorana nature of neutrinos, the absolute mass scale and the

... sibility of CP violation in the lepton sector are still open questions. We present the experimental program for the following years.
