The town is part of the SalzburgPongau region. It is located in the valley of theEnns River, near the confluence with its Taurach tributary, at the foot of Roßbrand mountain, part of theSalzburg Slate Alps. In the south the road runs parallel to the Taurach stream up toUntertauern, theObertauern ski resort and theRadstädter Tauern Pass at 1,738 metres (5,702 ft), which marks the border with the SalzburgLungau region. In the east, the Ennstal road leads toSchladming inUpper Styria.
The municipal area comprises thecadastral communities of Höggen, Löbenau, Mandling, Radstadt proper, and Schwemmberg.
In the 4th century before the Common Era the area was settled byCeltic tribes, theirNoricum kingdom was incorporated as aRoman province about 15 BC. The road across the Tauern Pass was part of a majorRoman road, leading fromAquileia inItaly to the city of Iuvavum (present-day Salzburg) in the north.
Styrian Gate and Capuchin Tower
A place calledRastat (i.e. "resting place") was already mentioned in a 1074 deed. The fortress of Radstadt was founded in the 13th century, when the Pongau region became part of theArchbishopric of Salzburg and border conflicts arose with theHabsburg dukes ofStyria; it receivedcity rights in 1289. The town served as seat of the local administration and was of significant value for the protection of the Enns Valley and the road crossing theAlpine crest viaRadstädter Tauern Pass towardsCarinthia andAquileia. Radstadt has aGothic church consecrated in 1417, and a town hall dating from 16th century.
Today Radstadt is also a popular tourism resort, with more tourists annually than the year-round population. It features its own ski area, and is part of an extended downhill ski and snowboard region (Ski Amadé) with links with the neighbouring town ofAltenmarkt.
