Okhta Center or phonetically Oḱhta-Tseńtr (Russian: О́хта-це́нтр), known before March 2007 as Gazprom City (Russian:Газпро́м-си́ти), is a failed construction project of a business centre in Saint Petersburg, Russia. It was supposed to include the first supertall skyscraper in the city. The 403 meters high main tower of Okhta Centre is set to be the tallest building in Europe amongst live building proposals. This project, remained unrealised, was supposed to house headquarters of the Gazprom energy company, along with museums, library, sports and leisure facilities, and a concert hall. It was to be build in the mouth of the river Okhta, on the right bank of the river Neva. Its 403-meter high tower was conceived not only as a dominant, but also as a new symbol of Saint Petersburg. It was to be completed by 2016. However, the project met fierce opposition from citizens, civil groups, and international organizations. When the project ideas were introduced to international jury, three out of four architects walked off the jury in protest, the competition was also boycotted by the Russian Union of Architects.
