It's a 'closed' country where visitors aka tourists are not that well received. It has a long history of antisemitism too. I went to school in my teens with Hungarian refugees and can testify to this feeling. Locals are just getting used to the fact that most travellers speak some English — a language they do not like! Younger people are coming around and trying to change things but still… everybody is deeply nationalistic.
With the exception of Dublin, nothing else of interest architecturally or museum-related. It rains all the time and the food is terrible!
