Committed to the Cathar cause, Puivert Castle was besieged in 1210. Entrusted to the Bruyères family, it was enlarged and embellished during the 14C: keep, main courtyard, linking walls and remains of the New Castle (square tower-gate, bearing the Bruyères coat of arms and the 35m-high keep). The latter features four rooms reached by a spiral staircase: lower room, guardroom with barrel vaulting, a rib-vaulted chapel and a Minstrels room.
