Blazon: Vert between two flanks* striped** argent and azure a horseshoe pendant or and a well of the second, water of the third
*The term in the blazon is Flanken, which seems to be a charge specific to Germanic heraldry. They may occur with the top, bottom, both, or neither curved, but the sides are always straight. Contrast the English flaunches, which are inevitably rounded.
**This is also taken from the original blazon; “striped” is rarely, if ever, used in blazoning in English.
The horseshoe represents a local festival in honor of St. Leonard of Noblac, patron saint of horses. The well (or Brunnen) both refers to the town’s name and the legend of its founding. Allegedly, Duke Tassilo III of Bavaria had lost his way in the woods when he stumbled upon a spring. In gratitude, he founded a church on the spot, which later became the town of Tesselbrun (Tassilo’s fountain) and later Desselbrunn.
