The Peace Palace has two towers, the highest of which was adorned with a clock donated by Switzerland. Several committed individuals and organizations have eventually made it possible to also place a carillon with 47 clocks in the tower. The last clock was donated in 2013 during the centenary celebrations of the Peace Palace. The carillon is owned by the Carnegie-Foundation, but the Hague Carillon Foundation organizes for it to be played. Throughout the year, the Peace Palace carillon is played every Tuesday and Thursday from 13.00 to 13.45 hours. On the occasion of the International Day of Peace an extra concert will take place with an appropriate programme. On the square (Carnegieplein) in front of the Peace Palace you can listen to the concert.
