  Photoproduction experiments are a key tool in the investigation of the
spectrum of hadronic states and the way gluons contribute to this spectrum. The
GlueX experiment, located at Jefferson Lab, features a linearly polarized
tagged photon beam and its detector system is optimized to measure a wide range
of neutral and charged final states. GlueX offers unique capabilities to study
the spectrum of hadrons and is dedicated to the search for hybrid mesons,
states with gluonic degrees of freedom. This talk presents first results from
our initial campaign of data taking which finished in 2018.
