Il 3 luglio 1958 fu firmato a Liegi un gemellaggio tra 6 città rappresentanti degli altrettanti Paesi fondatori della C.E.E. (Comunità Economica Europea, costituita a Roma con il Trattato firmato il 25 marzo 1957).
Tale gemellaggio plurimo chiamato "Ring of twinned cities" (Colonia, Esch-sur-Alzette, Liegi, Lille, Rotterdam, Torino) trovò fondamento nello spirito di solidarietà esistente tra le città coinvolte, nel forte senso di appartenenza alla comunità europea e nei profondi sentimenti di affinità in numerosi settori, quali l'economia, la storia e la cultura.
