The Virgo gravitational wave detector is an interferometer with 3 km long arms in construction near Pisa to be commissioned in the year 2000. Virgo has been designed to achieve a strain sensitivity (SNR = 1) of a few times 10(-23) Hz-(1/2) at 200 Hz, A large effort has gone into the conception of the mirror suspension system, which is expected to reduce noise to the level of 10(-21) Hz(-1/2) at 10 HZ. The expected signals and main sources of noise are briefly discussed; the choices made are illustrated together with the present status of the experiment.
