It is located in the historic Lungau region, in the valley of the upper Mur river, north of Katschberg Pass on the border with the state of Carinthia. With a population of about 3,500, St. Michael is the second largest municipality in Tamsweg District. The municipal area comprises the cadastral communities of Höf, Oberweissburg, St. Martin im Lungau, St. Michael im Lungau, and Unterweissburg.
The Lungau region has been continuously settled at least since the Bronze Age; the local Hallstatt culture was gradually assimilated by Celtic immigrants about 450 BC. After the Celtic kingdom of Noricum became a Roman province in 15 BC, a road was laid out across Katschberg Pass, leading to the city of Teurnia in the south. In the 6th century AD, Slavic tribes moved into the area, succeeded by Bavarian settlers 200 years later.
The Heihsgut manor house in the village of St. Martin, first documented in 1478, is one of the oldest preserved dwellings in the Salzburg Alps. Like several other Lungau municipalities, St. Michael is known for its annual Samson parades.
