The fiftieth anniversary of the signing of the agreement between the Govern- ment of Chile and ESO to set up a new observatory occurred on 6 Novem- ber 2013. The anniversary was marked by a formal occasion in Santiago, more informal celebrations at all the ESO sites in Chile and by visits from two European astronauts. A round-up of the anniversary events is presented. Figure 2.
