The Large Hadron Collider (LHC) operates with13 TeV center of mass energy and increasing luminosity at world record conditions. Apart from the discovery of the Higgs boson in 2012, several other particles were studied and many results were obtained. The top-quark is by far the heaviest known elementary particle. Its lifetime is significantly shorter than its hadronisation time, resulting in a behaviour unique among all quarks. In this colloquium, recent results and highlights of the ATLAS experiments with particular focus on physics of the top-quark will be presented.
