The Cortona-week experiment was initiated in the far 1985 and held yearly till now, and be honour to the ETHZ as the unique school in the world to host and financially support something like that. However, the ETH direction decided to stop it after 2017. We, the Cortona-friends, decided that this was not the right moment to stop such an experience, whose main aim is the fostering of a new generation of world leaders. This goal is too important to be abandoned, particularly in this period of general political and moral instability. And we (the newly grounded association Cortona-friends) decided to continue the work.
