The Hague International Open Day

The Hague is globally known as the international city of Peace and Justice. This is partly due to the many international organizations in the city and the important work they do to make the world safer and better place. Obviously, this happens behind the scenes. Within the walls of the organizations, such as the International Criminal Court, Eurojust, the OPCW and the courts in the Peace Palace. One day a year we pay attention to this important work and the organizations open their doors to the public. This is during the Hague International Open Day, which will take place on Sunday, September 23 this year.

During the visits you will learn more about the various forms of justice, international security and human rights. The Hague International Open Day always takes place on the Sunday before or after 21 September. On that day we celebrate the International Day of Peace of the United Nations.
