Medieval Underground Passageway at Castella

Looking to get away from it all and learn about history? Need a breath of fresh air? Come discover this marvelous site—the only underground site open to visitors in Occitanie—and let a costumed guide take you on a unique journey into the heart of a place steeped in mystery and emotion.
It dates back to the Middle Ages; all that remains of Sicard Alaman’s 13th-century fortress are a few sections of wall. But the real story unfolds below, in the underground chambers of the Castella. Stretching 142 meters long and perfectly preserved, it features features rarely seen in the underground passages of other castles: living quarters, grain silos, water sources, lamp niches...

Come experience the magic of the Castella underground with the story of Jeanne La Faussaire—a tale full of wonder and adventure that you can’t experience anywhere else!
