This is part 1 of 2 of a walking tour conducted by Viking Cruises showing the UNESCO world heritage historic windmills at Kinderdijk, the Netherlands. This is apparently the oldest collection of windmills in the Netherlands still in existence and in operation. These windmills date to 1738 and 1740. Amazing. Highly recommend visiting this site. Sorry that there is not more audio--Viking does their tours with Quietvox devices where you hear the guide through an earpiece. Starting at about 30:30, we are at the visitor center where there is a short video explaining the windmills operation and purpose and thereafter at a lecture explaining the maintenance of the windmills. One of the many amazing aspects of this is that families still apparently live in these windmills and have to make sure the sails are "down" when they leave their homes for whatever reason. It was really amazing to experience this in person--I hope my video gives some sense of what it was like but this is something I highly recommend doing. This was one of the highlights of our Rhine Cruise.
