Naardermeer near Naarden. The protected nature reserve has existed for about 4000 years and was formed by the river Vecht. Amsterdam's intention to use the area as a garbage dump led to the establishment of the Association for the Preservation of Nature Monuments in the Netherlands, which purchased the area in 1955 for 155,000 guilders..© 15 mei 2019 Aerophoto-Schiphol Aerial Photography
