The Radstadt town walls are among the most intact medieval fortifications in the eastern Alps. The almost square circuit, the three round corner towers — Kapuzinerturm, Mauttörl, Hexenturm — and the two gate towers all survive from the late thirteenth and fourteenth centuries. The walls are still mostly free-standing and can be walked around in twenty minutes.
The Hexenturm — the Witches' Tower — at the south-west corner gets its name from sixteenth-century witch trials held in the cellars below. It now houses a small local history collection. The walls are floodlit at night, when their square outline against the dark slopes of the Tauern is the best view in town.
