  MACRO was a multi-purpose experiment that took data from 1989 to 2000, at the
underground Laboratory of Gran Sasso (Italy). MACRO gave important
results/limits concerning: (i) the oscillation of atmospheric neutrinos, also
in the non-conventional scenario of violations of Lorentz invariance, (ii) the
searches for exotic particles (supermassive GUT magnetic monopoles,
nuclearites, WIMPs), (iii) muon physics and astrophysics. A summary of the
MACRO results will be presented and discussed, focusing the attention on the
exotica searches.
