  The status of topology on the lattice is reviewed. Recent results show that
the topological susceptibility chi can be unambigously determined. Different
methods, if properly implemented, give results consistent with each other. For
SU(3) the Witten-Veneziano prediction is confirmed. Preliminary results for
full QCD are presented. The problem there is that the usual hybrid montecarlo
algorithm has severe difficulty to thermalize topology. Possible ways out are
under study.
