Coastlines along the Dutch-German-Danish coasts were significantly changed during and by a huge storm tide, the Saint Marcellus' flood – also referred to as the Grote Mandrenke – that occurred on 16 January 1362. Many villages and towns were lost. The outlines of Strand changed significantly, nowadays legendary Rungholt reportedly being amongst the now sunken places. The Hallig island of Südfall was then separated from the mainland.
