I don't see anything Christian in the style of this wooden architecture either. Now tell me what's so Christian on them? If someone puts a Buddhist sign on the shield, it won't make the building Buddhist as such.
As I said.. Slavic culture = wooden culture. 1000 years ago Christianity was a thing of nobility and missionaries. And maybe you haven't noticed but Pagan practices are still normal http://www.slavorum.com/index.php/topic,2066.msg23745.html#msg23745 . Or you think that all of those superstitions are Christian because people are officially Christians now? Or why do people look for 'witches' while having a problem? The church is one thing and their life is the other thing. There are tons of proofs of Slavic Pagan past, but you focus just on temples. That says a lot.
Barov – does it change anything?
