The city of Biel/Bienne is known for its bilingualism (French and German) and as a language laboratory, it is given a model character. The exhibition (Le bilinguisme n’existe pas) examines the effects of this multilingualism in the fields of economics, politics, education and culture. Besides, are 50, 100 or even more languages spoken in this city today? Language mergers and mutual acceptance are as common as language barriers and conflicts. Are languages growing together in the age of migration and WhatsApp communication and other modern technologies? The old and new languages of the city are covered with all the senses in this exhibition, even by smell.
