The Noordeinde Palace in The Hague is an old palace with some modern twists. Queen Beatrix of the Netherlands had the palace renovated before starting using it in 1984. Unlike her ancestors she used the palace as a working palace. Over the years she collected art by especially Dutch artists in the palace. In one of the dining rooms there is, I guess, an earlier addition, the heads of Queen Emma and Queen Wilhelmina (or is it Queen Wilhelmina and Queen Juliana)?
King Willem-Alexander and Queen Máxima of the Netherlands did it their way. On one of the pillars in the hall downstairs one will find a cute train on the (fake) marble. More royal are the portraits of the royal couple and of their daughters above the entrance of the Indian Hall. And furthermore in the vestibule upstairs one will find the Golden Coach. It is a bit of a search to find everything, but with a little bit of help of staff and other visitors, and somewhat of a good camera, you will be able to spot them all.
