The controversial Okhta Center has received approval from the St. Petersburg government to start construction. St. Petersburg governor, Valentina Matviyenko, signed a document allowing for an exemption to the long-standing rule that limits buildings in the St. Petersburg center to a height of 100 meters. The building, when completed, will be the tallest in Europe. Plans call for the tower to be finished in 2013.
