SHiP (Search for Hidden Particles) is a new general purpose fixed target facility, proposed at the CERN SPS accelerator. In its initial phase the 400 GeV protons beam will be dumped on a heavy target with the aim of integrating $2\times 10^{20}$ protons on target in five years. A dedicated detector downstream of the target will allow us to probe a variety of models with the light long-lived exotic particles and masses below O(10) GeV/c$^2$. Another dedicated detector will allow the study of active neutrino cross-sections and angular distributions. In particular, the neutrino deep-inelastic cross-sections will be performed with a statistics 1000 times larger than currently available, with the extraction of the $F_4$ and $F_5$ structure functions, never measured so far. Tau neutrinos will be distinguished by anti-neutrinos, thus providing the first observation of the tau anti-neutrino. With muon neutrinos it will be possible to study the strangeness content of the nucleon.
