Sokolnicheskaya Line
Frunzenskaya () is a Metro station on the Sokolnicheskaya Line in Moscow, Russia. The station was opened on 1 May 1957 as the first stage of the extension of the Frunzenskiy radius. As the radius follows the bend of the Moskva river, the whole segment had to be built very deep (42 metres/138 ft for Frunzenskaya).
