Abstract: The Large Volume Detector (LVD) in the INFN Gran Sasso National Laboratory (LNGS), Italy, is a nu observatory mainly designed to study low energy neutrinos from the gravitational collapse of galactic objects. The experiment has been monitoring the Galaxy since June 1992, under increasing larger configurations: in January 2001 it has reached its final active mass M = 1 kt. Next year it will celebrate twenty years of operation. No burst candidate has been found over 6314 days of live-time, since June 6$^{th}$ 1992 to March 27$^{th}$ 2011, resulting 90 per cent c.l. upper limit to the rate of gravitational stellar collapses in the Galaxy (D $\leq$ 20 kpc) is 0.13 y$^{-1}$. Since July 2005 LVD participates to the Supernovae Early Warning System (SNEWS), the network of SN neutrino observatories whose main goal is to provide the astronomical community with a prompt alert for the next galactic core collapse supernova explosion. Since 2006 acts as a far beam monitor for the Cern Neutrinos to Gran Sasso (CNGS) project, the high energy, wide band nu/mu beam, set up at Cern and sent towards the LNGS. Possible upgrade of the experiment have been studied and discussed in the last years.
