The status of advancement of the Virgo project is presented. The first generation results from the Pisa seismic noise super attenuator give an upper limit to the noise transfer function of 2 x 10 to the -8th at 10 Hz. The scheme and the related problems of the Virgo interferometer, which is supposed to work down to 10 Hz, are given. A method for overcoming the effects of the scattered light from the interferometer vacuum pipe walls is proposed.
