I was wondering lately if some Poles remained Pagan afterwards
Some traditions remained, especially in the Kurpie region and parts of Podlasie. But very
discreetly. Some customs like casting wreaths into water on the solstice and throwing water at young women on Easter Monday to make them fertile are common throughout Poland today.
If you want to know about the neo-pagan scene, you could check out taraka.pl - it's largely about shamanic paths, but with some useful contacts for neo-paganism. Most of the users of that site speak some (or even a lot of) English.
The word "pagan" comes to us from the word "paganos" which meant "countryside" and this is because when the Roman Empire converted to Christianity it took much longer for the people in its rural areas to abandon practicing the rites of the old faith
Yeah, we know. So does the dictionary.
