Probing quantum gravity: Experimental tests of Lorentz and CPT symmetries

I review briefly theoretical reasons for possible violations of Lorentz and/or CPT symmetries in some models of quantum gravity. I then proceed to describe experimental tests, ranging from sensitive probes of quantum mechanics, like neutral kaons, and precision measurements in nuclear and atomic physics (clock comparison experiments) and antimatter factories (such as antihydrogen production at CERN), to astrophysical tests (gamma ray bursts etc) and neutrino physics facilities. I pay attention to discussing the sensitivity of the various facilities to Planck scale Physics. The results are optimistic in the sense that some models of Planck scale quantum gravity are already excluded and some others will be within experimental reach in the immediate future.
