This paper explores linguistic landscapes and the enactment of public visibility and presence of non-majority linguistic groups in EU member states. Non-majority linguistic groups gain power, visibility and presence through the introduction of bilingual or multilingual signposts on roads, streets, squares, and public buildings in towns and cities where a given linguistic group represents a significant population share. The article offers a comparative analysis of language policies of EU member states regarding enactment of official bilingual or multilingual signs in public space. Twenty EU member states have signed the "European Charter for Regional or Minority Languages," while 17 members have ratified it. In addition, the Charter of Fundamental Rights, an integral party of the Lisbon Treaty, stipulates that language diversity is one of the fundamental values respected by the EU. Hence, this comparative research assesses various practices employed by member states in relation to the proclaimed values of multilingualism. Consequently, the paper depicts and compares different language policies that produce linguistic landscapes in EU member states. Finally, it tries to determine whether there is a convergence towards a common EU policy on bilingual and multilingual signs in public space.
