The town can be proud of its connection to settlements dating back to the Neolithic Age. Ever since then, not only has the town evolved but so has its name, meaning "slowly running water". 8 September 903 is a memorable date, as then the town was officially mentioned in a document for the first time. Several years later the town was destroyed but was resettled. Centuries later the Ottomans razed the town yet again, afterwards, the Black Death killed many in 1679. Still, Mödling managed to survive, the population rose and successfully rebuilt its heritage.
In 1343 the town was granted the rights to be a Market town by Duke Albrecht II and in 1875 it was officially declared a city.
