Palais Augarten is a Baroque palace in the district of Leopoldstadt, Vienna, Austria. Constructed in the late seventeenth century by Johann Bernhard Fischer von Erlach on the site of a hunting château and gardens, the palace and gardens were expanded in the nineteenth century under Emperor Franz Joseph I of Austria. Despite extensive damage suffered during World War II, the palace has been maintained almost in its original appearance, and many of the original furnishings can still be found there. Today, Palais Augarten is the home and rehearsal space of the Vienna Boys' Choir, who also have their own school there. The palace is located on 130-acre Augarten park, which is the oldest Baroque garden in Vienna.
Until the 18th century, the present-day Leopoldstadt district consisted of forestland used by the Emperor and his court as a hunting ground. In 1614, Emperor Matthias built a hunting château on the site. In 1649, Emperor Ferdinand III added a Dutch-style gardens. Under his successor, Emperor Leopold I, the Augarten area saw increased settlement by nobility and Carmelite monks and eventually became part of Vienna. In 1677, Leopold I, who gave his name to the district (Leopold's City), added an extensive Baroque garden to the hunting château of his predecessors. In 1683, during the Battle of Vienna, Turkish forces used the area as a military base, and by the end of the war, the Baroque gardens were completely destroyed.
In 1688, the Augarten hunting château was sold to businessman Zacharias Leeb, who hired Johann Bernhard Fischer von Erlach to construct a palace on the site. Augarten park remained the possession of the Emperor. Palais Augarten was completed in 1692, and was originally called "Palais Leeb". In the coming decades, the palace was expanded and remodeled several times, changing owners more than once. In 1712, Emperor Charles VI hired landscape gardener Jean Trehet to redesign the Baroque park in the French style.
