Peace Palace Library

The Peace Palace is the monument for peace and justice: a symbol of world peace. The Peace Palace is home to not only the International Court of Justice and the Permanent Court of Arbitration, but also to the Peace Palace Library. Visit the Peace Palace Library during The Hague International Open Day on Sunday September 24 and meet historical figures who have provided an important contribution to the library and international law.

The Peace Palace was initially built to accommodate the Permanent Court of Arbitration (the Palace was built between 1907 and 1913), but for benefactor Andrew Carnegie, who contributed financially to the construction of the Palace, the creation of a library for international law was almost as important. The importance of the Peace Palace Library which was accessible to the public was therefore emphasized from the beginning.

Today, the Peace Palace Library is one of the largest libraries on public and private international law. The library also holds a big collection on international politics and relations, European law, as well as special collections on both the international peace movement and Hugo Grotius. During the Hague International Open Day special attention will be paid to these collections. Follow in the footsteps of Hugo Grotius, Tobias Asser, Bertha von Suttner and Andrew Carnegie and take an exclusive look at some of our oldest prints!

Most organisations have strict security. Because of this, we have added a list of the DO’s and DON’Ts for you. As a visitor, you’ll be required to follow these. You will receive your security passes a week beforehand via e-mail. We ask you to please print these out and bring them with you. The security of the organisations can ask you to show your passes. Although the chance is there that registration will be enough and you will not be asked to show your pass. At all times you are required to bring a legal personal ID, like a passport of a ID-Card. Bus-, library, etc. cards are not valid identification. Security checks take time, so please keep this in mind when visiting. We ask for your patience for any eventual waiting times.


  • Bring a valid ID like a password.
  • Bring a printed version of your access card.
  • Keep in mind that security checks can take some time.
  • Listen and comply with security.


  • Do not bring large bags.
  • Do not bring prams unless absolutely necessary.
  • Do not bring electronic devices.
  • Photos and video recordings aren’t always permitted.
