The Muslims (Tartars) have been there since the 8th century. I believe there are only 5 mosques in Russia. We have more churches in our little Town.
Out of date article but there is a hell of a lot more than “5 mosques in Russia” proper. In the muslim territories controlled by russia (such as Chechnya) there are numerous mosques.
