The third campus, Campus des Nations, had two beginnings. The first was in the 1940s with Rigot, which subsequently became Pregny-Rigot, and the second in 2005 with the closure of Rigot and the opening of the purpose-made buildings at Saconnex. The Pregny-Rigot campus was a pre-Kindergarten through year 6 school that adopted the International Baccalaureate Primary Years Program in 2002. This campus had two buildings, Rigot (an old Swiss farmhouse near the "Place des Nations"), and Pregny, a modern architectural structure, adjacent to the United Nations' premises and close to the International Committee of the Red Cross. In 2005, Pregny-Rigot shifted with the opening of a new building at Saconnex, near the World Health Organization and the International Labour Organization. The early childhood classes at Rigot were moved to a renovated Pregny and Rigot was returned to the city of Geneva. Years 3-6 were moved from Pregny to the new building, Saconnex, which also opened a secondary school. The Secondary school offers the IB's Middle Years Programme, the IB Diploma and the IB Career-Related Programme (IBCP).
