This palace is really small. First, its predecessor was the city hall of Amsterdam, and then it was transformed into a palace about two hundred years ago, so it was really the same size as the ordinary city hall, with very few rooms. Then it only opens for three months every summer and closes completely at other times. It is estimated that the royal family will go on vacation in summer, so it will be open for you to see. It seems that the theme of the exhibition is different every year. For example, the theme of 2016 is portrait. From the earliest oil paintings of William Orange to the collective photographs, the exhibition is in chronological order. Anyway, you can see it here, but don't really look forward to it as a magnificent palace.
