The walking tour of Kinderdijk, a UNESCO World Heritage Site, was a very learning experience. I discovered the real reason why the windmills were placed along the canals – to pump the water uphill to the river systems and prevent the lowlands from flooding. The tour inside the windmill museum was quite enjoyable as long as you were careful on the very steep staircases. It was really neat to see the giant vertical wooden beam rotating in the centre of the mill – the connecting piece between the gears at the top being turned by wind power and the gears at the bottom dealing with the movement of water. The whole Kinderdijk area is situated on a polder, which is a word that is defined as a piece of low-lying land reclaimed from water and protected via dikes and water pumping.
- 19 windmills (used to be 20) pumped/currently pump water uphill to the river in order to keep the low agricultural lands fertile and above water. The windmills have to run continuously to prevent flooding.
- The windmill wind blades could be put in at least 4 different positions to signal to view-able windmills the weather and other things.
