Palais Schwarzenberg is a baroque palace in Vienna. It is owned by the princely Schwarzenberg family.

Construction started in 1697 under the architect Johann Lucas von Hildebrandt and finished with alterations in 1728 under Johann Bernhard Fischer von Erlach. In 1751, a riding school and an orangery were added. The richly-decorated Marmorgalerie (marble gallery) is one of the largest features in the palace.

Today, parts of it are a five star hotel and the building is used for festivities and events.

A Palais Schwarzenberg in Prague also exists near the cathedral on top of the hill. {Wikipedia Article}
