The mythical figures on the balustrade are the work of Bartholomäus van Opstal and Johann Fröhlich. The copies of the famous “Borghese Fencer” are attributed to Andreas Götzinger (the inner pair) and Michael Bernhard Mandl (the outer, artistically more valuable pair). The pedestals bear the coat of arms of Salzburg’s Archbishop Johann Ernst Graf Thun (1687 - 1709). The elaborately decorated vases on the balustrade were built after plans by Fischer von Erlach.

The Heckentheater (Hedge Theater) is located on the west side of the Gardens. Built between 1704 and 1718, it is one of the oldest hedge theaters north of the Alps.

The Zwerglgarten (Dwarf Garden) dates back to Archbishop Franz Anton Graf Harrach, who had a dwarf theater with 28 dwarves set up southwest of the palace. Unfortunately, nothing is known of the creator of these “mysterious figures". These pitiful, misshapen beings, attached to almost all of the Baroque European courts for entertainment purposes, were highly respected and well-treated because of their integrity and loyalty. The dwarves in the Mirabell Gardens, made of Untersberg marble, are representative of these grotesque characters.
