I agree with the author, I was in Paris this year, at first I did not understand what kind of building it was, but after looking at the domes I realized, well, what did you really want, look at the opening of the Olympics in Paris and understand who rules the ball.
I was pleasantly surprised to see the Orthodox Holy Trinity Cathedral of Obor next to the Eiffel Tower. not quite the usual architecture. They explained to me that this was not only a cathedral, but also a spiritual and cultural center, where we were pleased to visit the exhibition of Sergei Andriyaka, which was on display at that time. The center has a library, Russian language courses, and a cinema room. It was nice that native speech could be heard on the territory of the complex. I even managed to visit the service. Weddings and baptisms are held in the church.
They accidentally wandered in there in the evening, before leaving back towards Russia. We read the Akathist to Nicholas the Wonderworker alternately in French and Russian! Charming!
