The commissioning phase of the Virgo gravity-wave interferometric detector started in September 2003, and is still progressing towards the objective to achieve a stable operation of the detector, at its design strain sensitivity. In October 2004 the interferometer was locked for the rst time in the recycled conguration, with the laser power reduced by a factor of 10. In April 2006, after some important modications of the input optics, the commissioning was able to continue with the full beam power restored. This new phase was also characterized by a strong boost to the noise hunting activity. From September 2006, at the time of this conference, monthly science run were planned to test the detector performance and reliability, and to prepare the transition to the long scientic data taking period which is foreseen for 2007 in coincidence with LIGO. In this article the main features of Virgo, together with its actual status and the plans for its future upgrade, are presented.
