  The poster presented the OPERA experiment and the SPL-Fr\'{e}jus neutrino
super beam project. OPERA (1) is an experiment willing to see tau neutrino
appearance. The detector is described in section 2 and the expected results are
given. Section 3 is devoted to the SPL neutrino super beam (2), which search
for $\theta\_{13}$. An optimisation of the SPL energy is proposed.
