Riff Todos Búlder 3 vías en zona artificial

The Zuiderzeewet that made it possible to construct the Flevopolder took effect on 14 June 1918. In 2018, to celebrate the hundredth anniversary of this Act, Bob Gramsma designed the Riff, PD#18245 monument. Like a gigantic, raised chunk of clay it sits on a flat, former agricultural plot in Dronten.
