The Hague International Open Day

The Hague’s international organisations work hard at making the world a safer and better place. Of course, this work goes on behind closed doors within the walls of the many international organisations that have a home in this city, such as the International Criminal Court, Eurojust, OPCW, and the courts in the Peace Palace. One day each year, you can visit these unique institutions. This year, The Hague International Open Day takes place on Sunday 23 September.

Learn more about various forms of jurisdiction, human rights and international security.
