The Russian Orthodox cross or Orthodox cross (in Russian use only) is a variation of the Christian cross since the 16th century in Russia, although it bears some similarity to a cross with a bottom crossbeam slanted the other way (upwards) found since the 6th century in the Byzantine Empire. The Russian cross has three horizontal crossbeams, with the lowest one slanted downwards. Nowadays it is a symbol of the Russian Orthodox Church and a distinctive feature of the cultural landscape of Russia. Other names for the symbol include the Russian cross, and Slavonic or Suppedaneum cross.
