St. Lucia's flood

[2] This disaster was similar to the North Sea flood of 1953, when an intense European windstorm coinciding with a high tide caused a huge storm surge.

The coming into existence of the Zuiderzee was the undoing of the powerful medieval trading city of Stavoren on the right bank of the now disappearing river Vlie, and the making of first the IJssel Hanse-cities of Kampen, Zwolle, Deventer, Zutphen, and Doesburg, and later the anti-Hanseatic city of Amsterdam, which began its rise from nothing almost immediately after the St. Lucia's flood.

After the flood, Harlingen, about 25 kilometres southeast of Griend and formerly landlocked, came into existence as the new seaport of Friesland, a role it kept for seven centuries.

Shortly after this annexation, the West-Frisian cities of Hoorn and Enkhuizen began a rise to prominence that would last until the 17th century.

It killed hundreds of people in England,[5] e.g. in the village of Hickling, Norfolk, where 180 died and the water rose a foot above the high altar in the Priory Church.
