Interesting facts..
William III used the palace’s gallery for meetings with spies and military planning, so parts of it functioned as a political nerve center as much as a home.
The palace has long served as a residence for royals outside the main line of succession, which is why it was sometimes described as a sort of royal “dormitory”
