One of the most impressive engineering works of all time that connects Friesland and North Holland: 32 km long, closed the passage of water to the Wadden Sea (Unesco heritage), thus transforming the Zuiderzee ('South Sea') ) in the IJsselmeer lake.
It is certainly worth following it and stopping at the vantage point to see also the evident difference of the currents in the two seas and their difference in altitude.
