The Large Hadron Collider (LHC) is an accelerator with a circumference near Geneva/Switzerland in which protons will be brought to collisions at a centre-of-mass energy of 14 TeV, an energy 7 times higher than what has been achieved so far. This unprecedented energy will allows us to probe many questions about the Nature of the fundamental constituents of matter and the forces that act between them. It is expected that the LHC will tell us about the mechnaism of electroweak symmetry breaking by which particles acquire mass and possibly also about the Nature of Dark Matter and about new symmetries or spacial dimensions that might be present. After the first succesful circulation of individual beams the LHC suffered from a major incident that unfortunately prevented any proton-proton collisions this year. Iis now scheduled to start collisions in Summer 2009. In this colloquium I will review the physics goals of the multi-purpose LHC experiments ATLAS and CMS, and I will describe the status of both the accelerator and the detectors with particular focus on the ATLAS experiment.
