Experience the International City of Peace & Justice

Discover the secrets of the International City of Peace and Law during the Just Peace Open Day 2026!

From the Peace Palace to the International Criminal Court, from the UN International Residual Mechanism for Criminal Tribunals to the National Monument Oranjehotel, the streets of The Hague breathe history! But what happens day in, day out behind those grand doors? And how do people working in The Hague contribute to a better, fairer world? Come along to the Just Peace Open Day 2026 to find out!
