Sometimes i've a problem with russian cards.... the information is all in cyrillic and, of course, i don't understand any cyrillic. My 1st problem was to find out the name of the city where this church is located. Svetlana's handwriting wasn't that difficult to read but the name of the city wasn't that clear. After some tries, i discovered that this is a card from Irkutsk.
RU-183299, sent by Svetlana.
Irkutsk is one of the largest cities in Siberia and the administrative center of Irkutsk Oblast, situated 5,185 kilometers (3,222 mi) by rail from Moscow.
After some tries too to identify this church, i believe this is the Ascension Church (1747-51).
