This initiative promoted by ICOM (International Council of Museums) linked to UNESCO is celebrated since 1977. This year's motto is "Museums for Social Harmony". ICOM defines museums as "an institution in the service of society and of its development" and the chosen topic wants to express that "museums are an important means of cultural exchange, enrichment of cultures and development of mutual understanding, co-operation and peace among peoples".
