The Anna Friso inlays
The inlays are small, secondary formed polders, which are placed behind the seawall where there is a risk of a collapse. Originally these were fields and meadows. Then a new dike was built inland, the material being previously excavated from behind the Oosterscheldedijk. Therefore the land became partly flooded and was thus no longer usable for farming. These deep wet marshes are simply beautiful, and very valuable natural areas.
