Last time we visited Holland we took a tour of the UNESCO site at Kinderjik. The Windmills of Kinderdijk are along the Rhine River in Holland south of Amsterdam. They are used to manage water and eliminate flooding and have been in existence since the 15th Century.
Our guide told us that this yellow wooden frame was to mark the spot where a National Geographic Cover was photographed. I don’t think that the yellow frame was placed by the Magazine but rather the tourist authority that manages the site.
