A visit to the medieval town is a must when visiting Carcassonne, but its ramparts and towers are also not-to-be-missed sites that will take you back in time. The Gallo-Roman towers, the oldest part of the walls, will take you back in time to Antiquity.
Another visit marked by the rich history of Carcassonne, the Château Comtal is nicknamed the "fortress within the fortress". With its many rooms, authentic period paintings, sculptures gleaned from all over the Aude and a projection retracing the castle's history, this is a visit well worth making.
And if you're still wondering what to visit in Carcassonne, there's still the Musée de l'École. Immerse yourself in a local school of yesteryear. From 1880 to 1960, take a trip back to the school of your childhood, or those of your parents or grandparents.
