The ICARUS T600 detector is the largest LAr-TPC operated to date. It performed a successful three-year physics run at the underground LNGS laboratories, studying neutrino oscillations with both the CNGS neutrino beam from CERN, and cosmic rays. Among the studies carried out on the beam events, a sensitive search for anomalous $\nu_e$ appearance was performed, while a disappearance analysis is just started on the collected sample of $\nu_{\mu}$CC. Both studies aim at verifying or excluding the experimental neutrino anomalies suggested by LSND signal and reactors and calibrations sources detectors. On the other end, cosmic rays triggers are used to study atmospheric neutrino interactions.
The T600 detector is now undertaking a significant overhaul at CERN, within the CERN Neutrino Platform, that covers most detector subsystems. It will be then redeployed to FNAL, where it will act as far station for the SBN project, dedicated to solving the sterile neutrino hypothesis. This contribution will discuss LNGS analyses, as well as the overhauling activities at CERN and the preparation for the new physics run in the United States.
