Traunviertel Region (Traungau, Traunkreis), Upper Austria, broadly speaking the catchment area of the River Traun with the Upper Austrian part of the Salzkammergut, or more precisely the area (alt. about 300-400 m) of the lower reaches of the River Traun between the Danube, the River Enns, the Alpine fringe and the Hausruck hills with the Attergau, the Welser Heide Plain and the Traun-Enns plain which borders on the plains of the rivers Traun, Enns and Danube. -Originally owned by the Traungau Counts (Otakare), this region was part of the duchy of Styria up to 1254. In the treaty of Ofen (1254) between Otakar II of Bohemia and Bela IV of Hungary it was separated from Styria and was called the "province beyond the Enns River" ("Land ob der Enns") later to become Upper Austria.
The Traunviertel Region is an alluvial plain formed by the Alpine rivers and glaciers consisting of moraine chippings, boulders and schlieren. The Welser Heide Plain and the Traun-Enns plain are two of the most fertile regions in all of Austria: wheat, rye, barley, sugar beet and maize are the main crops grown. The main industrial towns (Steyr, Enns, Linz, Traun, Wels, Lambach, Vöcklabruck, Lenzing, etc.) are situated along the main traffic routes (railway line Vienna -Salzburg, A1 motorway, Bundesstraße road Linz - Salzburg). Thermal spas: Bad Schallerbach, Bad Hall and Bad Wimsbach-Neydharting. The monasteries at Kremsmünster and St. Florian are fine examples of culture and art in the region. The main type of farmhouse is the four-cornered farmhouse.
