The All Saints Day Flood of 1436 (German: Allerheiligenflut) on All Saints' Day (1 November) 1436 was a storm tide that hit the entire North Sea coast of the German Bight. In the North Frisian village of Tetenbüll alone 173 people died. Eidum on the island of Sylt was destroyed; its inhabitants left and founded the village of Westerland as a result.
