Schielands Hoge Zeedijk

Constructed in the 13th century, the dike continues to protect an area inhabited by 3 million people from flooding by the North Sea.

The Schielands Hoge Zeedijk never really collapsed, though the All Saints' Flood of 1570 indicated its weakness.

On 1 February 1953, during the North Sea Flood of 1953, the dike almost collapsed between Capelle aan den IJssel and Nieuwerkerk aan den IJssel; the hole was filled by sailing a ship into the dike, an event commemorated by the monument Dubbeltje op zijn kant ("dime on its edge", a Dutch proverb indicating a dramatic event nearly happened).

It follows basically the Northern bank of the rivers Nieuwe Maas and the Hollandse IJssel.

The Hoogendijk is maintained by 'the Hoogheemraadschap van Schieland en de Krimpenerwaard' and classified as a primary waterbarrier.
