Originally called "Altenau", Mirabell Palace was commissioned to be built for Salome Alt by Wolf Dietrich in 1606. The "angel staircase" by Raphael Donner that leads to Europe's "most beautiful wedding hall" is of special interest.

The Mirabell Gardens contain groups of statues based on figures from Greek mythology. Other attractions include: "Dwarf Garden", Baroque Museum, Hedge Theatre. The gardens adjoin the Kongresshaus (Congress Center) and the Kurhaus (Paracelsus Health Spa).
