The account

On the night of January 16, 1362, the Grote Mandrenke, the Great Drowning of Men, tore the North Sea coast apart and took the town of Rungholt whole. For centuries it was half-legend, the drowned bells of the Wadden Sea. Then the tides began returning plough-marks, wells, and pottery; in 2023, geophysics found the church itself, two kilometres out under the mud. At low tide you can walk the flats above a town the sea keeps.
