The palace with its gardens is a listed cultural heritage monument and part of the Historic Centre of the City of Salzburg UNESCO World Heritage Site.

The Palace: a precious jewel
Prince-Archbishop Franz Anton von Harrach had Mirabell Palace redesigned by the famous baroque architect, Lukas von Hildebrandt, from 1721 to 1727, integrating the individual buildings into a self-contained complex. The palace was damaged by the great fire that swept through the city on April 30, 1818. A number of frescoes including those by Johann Michael Rottmayr and Gaetano Fanti fell victim to the flames. The grand marble staircase that led into the palace and the marble hall survived unscathed.

The Mirabell Gardens
The famous Mirabell Gardens were redesigned around 1690 under Prince-Archbishop Johann Ernst Graf von Thun to plans by Johann Bernhard Fischer von Erlach and completely remodeled around 1730 by Franz Anton Danreiter. The Pegasus Fountain, a work by Kaspar Gras from Innsbruck, was installed in 1913. The four groups of statues around the fountain were sculpted by Ottavio Mosto (1690) and symbolize the 4 elements: fire, air, earth and water. The Mirabell Gardens were opened to the public by Emperor Franz Joseph in 1854. Today they are a horticultural masterpiece and popular backdrop for photographers.
