The Radyanska or Sovetskaya (Ukrainian: ; Russian: ) is a station on Kharkiv Metro''s Kholodnohirska-Zavodska Line. The station was opened on August 23, 1975. It is located in the historical part of Kharkiv, beneath the Ploscha Konstytutsii, literally Constitution square, previously known as Soviet Square. The Radianska station forms a complex with the adjacent station, Istorychniy Muzei, on the Saltiv Line. Before the Istorychniy Muzei station''s completion in 1984, a relief marble architectural item adorned with the hammer and sickle was located on the station. Inside the passenger transfer tunnel is the Kharkiv Metro''s only public restroom, which is unlike the western European metro systems.
