Every single European country is pretty in some way. However, the prettiest of them all are the 2 countries: my own (UK) & my husband's country (by origin), namely Ireland, so I'd say they're BOTH the prettiest European countries to me. Besides, I may be living in Belfast & consider London for my capital, but to my husband Seán it's always been Dublin. We even have a flat (an appartment) in Dublin now! Surprised?
