FINAL RESULTS OF THE MACRO EXPERIMENT.

In this paper the main results obtained by the MACRO experiment are described: results on atmospheric neutrino oscillations, high energy muon neutrino astronomy, final stringent upper limits on GUT magnetic monopoles and nuclearites, searches for WIMPs, search for electron antineutrino burst from galactic stellar gravitational collapse, studies of the primary cosmic rays at knee energies and of the penetrating high energy atmospheric muons
