Life below sea level - Is it Wet?

Can find such signs all around Holland. This one is at Kinderdijk. One of the few locations where one can find windmills located in such breathtaking backgrounds.
Before going there, i thought, what is so beautiful about windmills? Well, on the way back i thought i should be here in all possible seasons to capture it.
