The Marble Bridge (or "Siberian Marble Gallery"[1]) is a decorative pedestrian roofed Palladian bridge (gallery walkway) in Empress Catherine Park[2] in the former royal residence Tsarskoye Selo (now town of Pushkin) near Saint Petersburg, Russia. It connects the Swan Islands — an artificial archipelago of seven islets in the landscape park of Tsarskoe Selo — spanning a rivulet flowing between several ponds.
The bridge was modelled after the Palladian Bridge (1736) in the park of Wilton House, in England, and served as a showcase for Ural marble. All the details of the bridge — including the granite Ionic colonnade — were produced in Yekaterinburg, transported to Tsarskoe Selo and then assembled in the workshop of Vincenzo Tortori in 1774.[3] It is probably called Siberian due to its construction with marble from the Urals.[3]
