Relics of the city were being found in the Wadden Sea until the late 20th century, but shifting sediments have carried the last of these into the sea. In the 1920s and 1930s, some remains of the city were exposed; they suggest a population of at least 1500 to 2000, which is fairly large for that region and time, and it is likely that Rungholt was a major port. Legend has greatly exaggerated its size and wealth, however.
Impressed by the fate of the city, the relics, and not least legend's excessive descriptions, the German poet Detlev von Liliencron wrote a poem about this lost city which starts with the words: "Heut bin ich über Rungholt gefahren, die Stadt ging unter vor fünfhundert Jahren". (Today I travelled across Rungholt, the City went under five hundred years ago)
Local myth has it that one can still hear the church bells of Rungholt ringing when sailing through the area on a stormy night.
