The New Michael Palace was the third Saint Petersburg palace designed by Andrei Stackenschneider for Nicholas I's children. It was built between 1857 and 1862 on the Palace Embankment, between the Hermitage Museum buildings and the Marble Palace.
The palace was commissioned by Grand Duke Michael Nikolaevich of Russia on the occasion of his wedding to Cecilie of Baden. The design is a Revivalist medley of quotations from the Renaissance, Baroque, and the Louis XVI styles. The Rococo interiors are ornate yet airy. The statuary is by David Jensen. Some of the paintings are by Michael Zichy.
