Russian Revival architecture

The Russian Revival style comprises a number of different movements within Russian architecture that arose in the second quarter of the 19th century and was an eclectic melding of Byzantine elements (Neo-Byzantine architecture in the Russian Empire) and pre-Petrine (Old Russian) architecture. Russian Revival architecture arose within a framework of renewed interest in national architectures which occurred in Europe during the 19th century, and it is an interpretation and stylization of the Russian architectural heritage.
