Windmills are Holland’s most recognizable structures. In second place is Rijksmuseum in Amsterdam. Since the art museum was founded in 1798, their priceless collection has grown to over one million pieces. The National Museum attracts about 2.5 million visitors each year. This small facsimile of Rijksmuseum is flawless in every aspect. Speaking of windmills, all 19 of the famous ones at Kinderdijk are miniaturized along a pretend canal at Madurodam.
