Blazon: Gules pointé in base or, three roundels counterchanged
The partition of the field is from the arms of the Lords of Goldegg, who held (disputed) control over the valley from 1272 presumably through the house’s extinction in 1449. The roundels are derived from the arms of Nonnberg Abbey, which formerly held possession of the village of Unterberg, one of the six villages included in the municipality. (You can see the abbey’s arms on the dexter here, though the tinctures are hard to make out; the sinister arms are those of the Schneeweiß family.)
Blazon: Per pale gules and azure two wings displayed argent, surmounted by three roundels in pile of the first, second, and third
The wings (and possibly also the division per pale) are derived from the arms of Michaelbeuren Abbey, though I’m not quite clear on whether those are the arms of the abbey itself, or the abbot Ulrich Hofbauer. (The positioning here suggests the abbey, though; I’d guess the sinister coat is the abbot’s personal arms. Traditionally, in ecclesiastical heraldry, the arms of one’s office take precedence over any personal arms.) The three roundels are a symbol of St. Nicholas, the town’s patron saint, albeit with a tincture swap; they are more usually depicted as bezants, the better to recall the story of the anonymous gift of three dowries.
Blazon: Per quarterly I and IV o five torteaux in orle, in chief a roundel of France (Medici), II and III gules a fess argent (Austria)
These are Marie’s arms from before her marriage. In a classic example of quartering, the first and fourth quarters display the arms of her father, Francesco I de’Medici, Grand Duke of Tuscany, while the second and third come from her mother, Archduchess Joanna of Austria. Since both parents were armigers, all of their children would have been entitled to bear their arms quartered. Upon marrying King Henry IV of France, she would have quartered his arms in the first and fourth quarters with the above arms in the second and third.
