MARIA ALM, Austria (Reuters) - Every year around St. Jacob's Day, men from Austria's Salzburg region grapple with each other in a natural arena at the top of the Hundstein mountain in a traditional martial arts contest - the Hundstoa, or Jakobi Ranggeln.

The Celtic wrestling tradition, which was included in UNESCO's cultural heritage list in 2010, goes back more than 500 years.
