France's most famous and evocative medieval citadel. Carcassonne is the third UNESCO World Heritage Site in the Languedoc-Roussillon. It is the scale of the castle at Carcassonne that blows you away. A wonderful monument with an impressive history. If you do go, try and keep your hand in your pocket as you go past all the lines of tourist souvenier shops - most of the stuff they sell is absolute tat and you don't really need it!. There are however some reasonably priced restarants inside the Cite - although I can't vouch for the quality. (see Carcassonne tourist site for more information).
