Saint George Cathedral, Yuryev-Polsky

Saint George Cathedral in Yuryev-Polsky is one of a dozen surviving white-stone churches which were built in Vladimir-Suzdal Principality in the northeastern Rus prior to the Mongol invasion. Constructed between 1230 and 1234, the cathedral was also the last of these churches to be built, completed just three years before the invasion. Unlike most of the other pre-Mongol Vladimir-Suzdal churches, the St. George Cathedral was not designated as the World Heritage site. The cathedral was designated by the Russian government as an architectural monument of federal significance (#3310181000).
