The luminosity upgrade of the Large Hadron Collider at CERN foresees a luminosity increase by a factor 5 compared to the LHC. To cope with the corresponding rate increase, the Muon System of the ATLAS experiment at CERN needs to be upgraded. In the first station of the high rapidity region, micromegas detectors have been chosen as the main tracking chambers but will, at the same time, also contribute to the trigger. We describe the R&D efforts that led to the construction of the first 2.4 x 1 m2 large micromegas detectors at CERN and outline the next steps towards the construction of the 1500 m2 of micromegas detectors for the ATLAS upgrade. The technical solutions, including the resistive spark protection, adopted in the construction of the two chambers as well as results on the detector performance with cosmic rays are shown.
