Whenever I see this picture I wonder what the man and the Royal Maréchaussée are talking about. The man in the background is looking at the two and that also draws attention to them.
Maybe the man just wants to cross the square: “How do I get on the other side of the fences?”
This photo was taken on the 4th of May which is Remembrance Day in The Netherlands. Across the palace is the National Monument where the king places flowers during the ceremony and the fences create a secure pathway. So when you want to cross the square you need to go around the back of the palace or the monument.
