Vorontsov Palace, Imperial palace in Odesa, Ukraine

Vorontsov Palace is an imperial building from the Russian Empire period in Odesa, Ukraine. The colonnade frames a courtyard, while stone lions flank the entrance and decorated friezes embellish the upper floors.

Built in 1826–1828 to a design by Franz Boffo in the Empire style, the palace was the residence of Mikhail Vorontsov, governor-general of the Novorossiya region, on the site of the former Turkish fortress of Khadjibey. In 1837 Vasily Zhukovsky visited and noted its library, whose books Pushkin had used before they were moved into the new hall. In 1854 Anglo-French ships bombarded Odesa and hit the palace with up to 200 cannonballs; one remains in the wall of today's ballet classroom. From 1936 it housed the Palace of Pioneers.

The Russian name of the building refers to the governor-general who lived there and shaped the city for many years. Visitors can view the exterior and see the columned facades that remain a landmark of the coastal district today.

The palace stands at Vorontsovsky Lane 2a, off Prymorsky Boulevard on the northern edge of the coastal hill. The belvedere colonnade behind the main building looks over the Odesa Bay. A cannonball from the 1854 bombardment is still lodged in the wall of the ground-floor ballet classroom.

During the siege in 1854, the Anglo-French fleet aimed its guns at the building's elevated location. Cannonballs struck the upper floors, and some of the impacts remained visible in the walls until later renovations concealed them.
