It may only be 108 years old, but the Hotel de la Cite, part of the MGallery Collection,  is the last and most decorative piece in the 1200-year-old jigsaw puzzle which makes Carcassonne such a fascinating place to visit. It was at the beginning of the 9th century that this ancient citadel got its name when it survived a siege by Charlemagne with the help of its moat, drawbridge and thick Roman walls.
