The Hermitage Theater, the oldest building of the Winter Palace Complex, was built on the site of the former Winter Palace of Peter I in 1711-1723. The theater itself was built later - in 1783-85 to the design by Giacomo Quarenghi and finished in 1802. The theater building is connected with the main palace by an arch over "Zimniaya Kanavka", the canal between the Moika River and the Neva River. The facade and hall decoration of the Hermitage Theater is unique and represents a classical masterpiece of palace architecture of the XVIIIth century.
