Windmills at Kinderdijk: Postcard Scenes and Innovative Water Management

Today’s excursion took us to one of the Netherlands’ most iconic and enduring symbols—the windmills of Kinderdijk. Standing on the embankment, gazing across the flat polder landscape dotted with 18 towering windmills, it was easy to see why this site is recognized as a UNESCO World Heritage Site.

Our group had several questions: 1) What is the purpose of the windmills in an age of electricity? 2) How long have these windmills be here? 3) Who lives in the windmills, and how are the residents chosen? 4) What is required to become a miller? 5) How are these windmills maintained, especially considereing their age?  Our guide answered these questions and more as we proceeded on our tour.

The story of Kinderdijk is one of ingenuity born from necessity. Much of the Netherlands lies below sea level, and for centuries, the Dutch have battled to keep the water at bay. In the 18th century, the people of this region built a network of windmills to pump excess water from the low-lying polders into the nearby rivers, preventing floods and reclaiming farmland. These mills worked in tandem, harnessing wind power to turn giant wooden gears and drive Archimedean screws or scoop wheels that lifted the water away.

Kinderdijk’s name comes from a famous local legend: during a devastating flood in 1421, a wooden cradle carrying a baby was seen floating toward the dike, a cat perched on top to keep it balanced. The “child’s dike” became part of local lore, a reminder of resilience in the face of nature’s challenges.

Though modern pumping stations have replaced most of the windmills’ practical functions, the Kinderdijk mills still stand—sturdy, graceful, and very much alive in Dutch heritage. As our guide explained, several are still operational and maintained by dedicated millers, their sails turning in the breeze just as they have for more than 250 years. One windmill is operated by an 11th-generation miller.

To become a miller, a student must go through a two-year program of study, even if the student was raised by a miller and has years of experience assisting with windmill operation. After the completion of their studies, a graduate then applies to reside at one of the Netherlands more than 1000 windmills. Some windmills are for processing grain, while the ones at Kinderdijk are strictly for water management.

Walking between the mills, we were struck not only by their beauty but also by what they represent: the Dutch spirit of innovation, cooperation, and respect for the land and water that shape their lives. Kinderdijk isn’t just a postcard scene—it’s a story of a people who have partnered with the wind to manage their water levels with green energy.
