Located just 10 miles outside of Rotterdam is Kinderdijk, one of the most authentic tourist destinations in the Netherlands. The village, located on the Alblasserwaard polder at the confluence of the Lek and Noord rivers, is home to 19 windmills that were built around 1740 to help control water and reclaim the land on which the polder sits. One of the best times to visit is during early September when for one week, the windmills are lit up each night from 8:30 to 11:30pm.
Kinderdijk was designated a UNESCO World Heritage site in 1997, in recognition of the contributions made by the Dutch to the technology of handling water here. Kinderdijk has examples of all the typical features associated with water-management technology, including dykes, reservoirs, pumping stations and the original windmills. A visit allows you to walk along the canals, up close to the windmills, many of which are still operational.
