Blazon: Azure issuant from battlements in sinister base argent a horse salient or langued gules
An old legend connected with the arms claims that in 1376, a knight from the region got roaring drunk and rode his horse out into the mountainous wilderness. After several days, the horse returned, covered in gold, and the locals managed to follow its trail back to one of the richest goldmines of in the area. The knight, however, was never seen again. The battlements supposedly derive from the arms of the lords of Wenns, but I cannot verify this.
I’m not sure why all the images I can find of these arms are kind of terrible. It’s a lovely blazon with an interesting story behind it, and it deserves a better illustration than I have been able to find.
