What is the Just Peace Open Day?
The Hague is known worldwide as the "International City of Peace & Justice," and almost every monumental building in the city plays a role in building a more just and peaceful world.
From the Peace Palace to the International Criminal Court, to the Oranjehotel National Monument, the streets of The Hague breathe history! But what actually happens behind those grand doors every day? And how do people working in The Hague help make the world a better and fairer place? That's why the Just Peace Open Day is here to find out!
For one special Sunday in September, around the International Day of Peace, Just Peace The Hague and more than 20 partners will open their doors to you for a look behind the scenes and to hear the stories of the people and history behind each institution.
