An unprecedented scientific milestone was recently reached - 1000 peer-reviewed papers have been published from each of the ATLAS and CMS experiments at the Large Hadron Collider at CERN in Switzerland and over 600 from the LHCb experiment. We propose a day to celebrate the LHC science and technology story so far. This will be a retrospective of the LHC science and technology, and a look ahead to the new technologies and the science questions at the LHC in the years to come.
