On 14 June 1918, the Zuiderzee Act came into effect, enabling the creation of the Flevopolder. To commemorate 100 years of the Zuiderzee Act, Bob Gramsma created the monument Riff, PD#18245.
Using three pile foundations and a complex structure similar to those used in bridge and boat construction, Gramsma piled 15,000 cubic metres of agricultural and Zuiderzee soil to form a hill. A large cavity was then dug into this hill, which was lined with a layer of sprayed concrete, fitted with a roof and a staircase. Afterward, the soil was removed down to ground level, leaving behind a cast of concrete mixed with remnants of the Zuiderzee soil.
Riff, PD#18245 is an imprint of Gramsma’s dug path through the Flevoland soil, reflecting the reclamation and artificiality of the polder.

Riff, PD#18245 is an imprint of Gramsma’s dug path through the Flevoland soil, reflecting the reclamation and artificiality of the polder.
Gramsma’s newly formed landscape, resting on piles like a building, provides shelter for animals and mosses. Visitors can ascend the small staircase to view the old land near Elburg and the new, man-made landscape with its dikes, roads, and ditches.
