LONG RING DIJK
The ring dike of Eastern Flevoland is approximately 90 kilometers long. The ring dike was constructed in separate
parts, dike sections or plots. Each plot was approximately seven kilometers long. The plots
were built towards each other, so that the dike finally closed completely. The last gap was closed
on September 13, 1956, after approximately 75 million cubic meters of soil had been incorporated into the long ring dike.
