In the summer of 2005, the exhibition Royal Summer in The Palace was put on. It focused on the artists Bruno Ninaber van Eyben and Peter Struycken, both of whom made sensational designs for the Dutch guilder and the Dutch stamp at the beginning of Queen Beatrix’s reign. The portrait of Queen Beatrix, which Peter Struycken designed for the Court of Audit in 1997, was enlarged on the facade of the palace.
