There are a lot of places with medieval architecture remained in Europe. But such unique as Eze - isn't enough. Its uniqueness is in it's distance location from the highway and it is high on the mountain. Therefore EZE isn't so strongly flooded by tourists and cars, as similar sights in Europe. It gives the chance not only to admire eyes, but also feel the spirit of the Middle Ages.
Best way to enjoy it - to have a lunch or dinner in any restaurant here. I recommend Chateau Eza - best view.
