The Mikhailovsky Palace is a grand ducal palace in Saint Petersburg, Russia. It is located on Arts Square and is an example of Empire style neoclassicism. The palace currently houses the main building of the Russian Museum and displays its collections of early, folk, eighteenth, and nineteenth century art.
It was originally planned as the residence of Grand Duke Michael Pavlovich, the youngest son of Emperor Paul I. Work had not yet begun on the Mikhailovsky Palace, when Paul was overthrown and killed in a palace coup that brought Michael's elder brother to the throne as Alexander I. The new emperor resurrected the idea for a new palace by the time Michael was 22, and plans were drawn up by Carlo Rossi to develop a new site in Saint Petersburg.
