Located in neighbouring France, the orangery at the Château de Voltaire will host a photo exhibition from Friday September 25, paying tribute to the agreement signed in 1956 between France and Switzerland. This treaty allowed Genève Aéroport to extend its runway from 2 to 3.9 km, while strengthening its international partnership by creating a sector within the terminal dedicated to flights to France. Authorities from both countries will mark the agreement with a joint speech at the opening of the exhibition.
