Walking on a sunken bridge... How cool that is?

I am sure all of you crossed so many bridges, but have you ever walked on an sunken one? This incredible bridge in southwest Netherlands parts the water so that pedestrian can walk in between. If you look far away, you cannot really tell that there is even a bridge existing. You can touch the water while passing through.  Isn't the architecture so cool?

Are you wondering what is at the end of the bridge? A beautiful 17th century castle...
