Permanent Court of Arbitration (PCA)

The Permanent Court of Arbitration (PCA) was established in 1899 to facilitate the peaceful settlement of international disputes. This was the single biggest achievement of the first Hague Peace Conference of 1899 and provided the impetus for the construction of the Peace Palace, where the PCA is based. The PCA is an intergovernmental organisation with a growing number of members, currently 121.

The PCA helps to resolve conflicts involving various combinations of states, state entities, intergovernmental organisations and private parties. The PCA’s Secretariat, the International Bureau, provides registry services and administrative support to tribunals and commissions. The number of cases (some 125) illustrates how varied the PCA’s remit is, encompassing territorial, environmental, and contractual disputes, as well as investment disputes arising from bilateral and multilateral investment treaties.


Opening times: 11.00 a.m.-5.00 p.m.

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.
