The name "Traun" itself is derived from the Celtic word for river. Traun has a long history dating back to the Neolithic Age. Evidence of this early settlement are ancient tombs and graves that were found on the Roman Road that once joined Wels to Lorch. In the 6th century AD the Bavarians came to Traun. The first rural settlement was founded around the Moated 12th century Traun Castle. These days long past, the economy of the area was heavily based upon fishing and milling. However, Traun owes its prosperity and much of its historic architecture to the paper and cloth industry that developed from the early 20th century. On May 21, 1973 the village was granted the Town Charter.

Highlights in the annual calendar of winter events are the atmospheric Christmas Market on Traun Castle, deeply rooted in tradition, and the spectacular Perchten Run. During the Advent Season, lovingly decorated stalls are positioned along the streets at St. Martin and Oedt, selling Christmas decorations and culinary delights. The spicy bouquet of hot mulled wine fills the crisp winter air, and spirits are high. This is where holiday momentum really builds!
