  The goal of LHCspin is to develop, in the next few years, innovative
solutions and cutting-edge technologies to access spin physics in polarised
fixed-target collisions at high energy, exploring the unique kinematic regime
offered by LHC and exploiting new final states by means of the LHCb detector.
The forward geometry of the LHCb spectrometer is perfectly suited for the
reconstruction of particles produced in fixed-target collisions. This
configuration, with centre of mass energies ranging from
$\sqrt{s_{\rm{NN}}}=115~\rm{GeV}$ in $p-p$ interactions to
$\sqrt{s_{\rm{NN}}}=72~\rm{GeV}$ in heavy ion collisions, allows to cover a
wide backward rapidity region, including the poorly explored high$-x$ regime.
With the instrumentation of the proposed target system, LHCb will become the
first experiment simultaneously collecting unpolarised beam-beam collisions at
$\sqrt{s_{\rm{NN}}}=14~\rm{TeV}$ and both unpolarised and polarised beam-target
collisions. The status of the project is presented along with a selection of
physics opportunities.
