It is one of the best examples of empire style in all Russia. Many people say that it resembles St Paul in Vatican but it is not. It is much more elegant; not gigantic but in harmony. Especially French Empire’s taken flags (Napoleon’s armies) and city keys from many French cities are worth to see. Probably you will be er see another real example of such historical objects. And if you will be lucky to hear the choir; you will be absolutely in love with this beautiful church. May God rest in peace souls of Emperors Alexander 1st, Paul and Marechal Kutuzovsky 🙏🏻
