Which of these countries, in your opinion, are the least "Westernised"?

Hard to tell because so much of eastern Europe has been opened up to tourism, and with that comes Westernisation. I think Albania because it was always the poorest Soviet Bloc nation, and hasn't been all that developed, and I would also say Ukraine, Georgia and Armenia for the same reason. Bulgaria has been opened up to tourism, but it has significant Muslim and Romany populations, which are a different culture to western Europeans, and it also has a different aplhabet.
