10 Euros - Willem-Alexander Kinderdijk

Issued to mark the inscription of the Kinderdijk windmill network onto the UNESCO World Heritage List, this piece was part of the Dutch mint's ongoing World Heritage series launched in the early 2010s. The Kinderdijk complex, comprising nineteen mills built around 1740, was constructed as part of a water management system for the Alblasserwaard polder — an area that sits several meters below sea level and has required continuous pumping for centuries.

Willem-Alexander had been king for less than a year when this coin was authorized, having ascended to the throne in April 2013 following Beatrix's abdication.
