1975, building site of the hydroelectric power plant in Nurek, Tajikistan. Built between 1961 and 1979 on the Vakhsh river, the earth-fill embankment dam of Nurek is the second tallest dam in the world (the tallest one is Jinping-I Dam, in China). The sign on the building read “СССР”, however this is actually Cyrillic and should read “SSSR”: it is the acronym of “Союз Советских Социалистических Республик” (Russian: Sojuz Sovetskich Socialističeskich Respublik) i.e. “Union of Soviet Socialist Republics“.
