  The announced ~ 3 {\sigma} enhancement in the inclusive {\gamma} {\gamma}
-spectrum at ~ 750 GeV made by the ATLAS and CMS collaborations at LHC might
indicate the existence of a monopole-antimonopole bound state: monopolium. In
here we revisit our calculation of 2012 from a more general perspective and see
that this resonance, if confirmed, might be a first signal of the existence of
magnetic monopoles.
