Building construction history
- The International Labour Office occupies its current location since 1974. The building, with ifs façade of glass and cast aluminum crowning a hill between the Jura mountains and Lake Geneva, represents the consolidation of a work started as an adventure for those who were its pioneers.
- The site was opened in July 1969. The first stone was laid in May 1970 and work continued until the end of 1974. The occupation of the building by the ILO was conducted from 18 November 1974 to 15 March 1975.
- ILO headquarters in Geneva was designed by a team of great architects - MM. Eugène Beaudoin (France), Alberto Camenzind (Suisse) et Pier Luigi Nervi (Italie) ; it has three main parts: the south wing, with the meeting rooms and library; the north wing, which includes general services, and, between the two, the central office building. These three blocks represent the three groups: governments, workers and employers - the underlying structure of the Organization.
