The town parish church, dedicated to the Assumption of Mary, sits on the highest point of the old town and is the architectural heart of Radstadt. The late-Romanesque core dates from the twelfth century; the gothic choir was added in the fifteenth. The most striking feature outside is the tall, slender west tower with its pointed roof.
Inside, look for the medieval baptismal font, the gothic crucifix above the main altar, and the small Lichtsäule (light column) on the church wall — a late-gothic stone shaft that once held an oil lamp marking the position of a chapel later demolished. The little surrounding churchyard is set in below street level and rewards a slow circuit.
