St. Lucia's flood

St. Lucia's flood was a storm tide that affected the Netherlands and Northern Germany on December 14, 1287 when a dike broke during a storm, killing approximately 50,000 to 80,000 people in the fifth largest flood in recorded history. Much land was permanently flooded in what is now the Waddenzee...

. The city was thereafter abandoned and from that time until the eighteenth century, Griend was inhabited by a few farmers, who built their houses on artificial hills. Around 1800, Griend still had an area of 0.25 km², but the island was moving to the southeast at a speed of 7 metres a year. By this time, all of its inhabitants had abandoned the island, and from then on was it used by inhabitants of Terschelling as a grazing area for sheep, and for the making of hay. The eggs of gull

Nowadays, the island is uninhabited with the exception of a cabin used in summer by birdwatchers and biologists. Griend is not accessible to the general public.

s, the island is slowly moving eastward. To prevent the island from vanishing altogether, some measures have been made to protect it: along its southern edge, a few dams were built, and around 1990 the island was strengthened by building a low sand dyke along the north side. Since then, the process of erosion has changed into a process of gradual growth.
