The worldwide community of museums will celebrate International Museum Day on and around 18 May 2017. The theme chosen for 2017 is “Museums and contested histories: Saying the unspeakable in museums“.
The objective of International Museum Day is to raise awareness of the fact that, “Museums are an important means of cultural exchange, enrichment of cultures and development of mutual understanding, cooperation and peace among peoples.” Organised on and around 18 May each year, the events and activities planned to celebrate International Museum Day can last a day, a weekend or a whole week.
Participation in International Museum Day is growing among museums all over the world. In 2016, more than 35,000 museums participated in the event in some 145 countries.
