The development of high intensity neutrino Super Beam is essential to study fondamental properties of these elementary particles and to discover matter/antimatter asymmetry in the leptonic sector. The European Spallation Source in construction in Lund, Sweden, will use a Multi Mega Watt proton driver which can also be used to provide such Super Beam. The ESS$\nu$SB project works on a neutrino long baseline facility using the ESS proton linac and a water Cherenkov detector. In the following, the main developments concerning the Target Station Facility will be be discussed.
