On the outskirts of Bizanet, in the commune of Montredon lies the Chateau Fort of St Pierre des Clars also known as ‘the Castellas’. There is nothing much left but the remains of the wall enclosing a square dungeon.

The chateau must have been built during the 9^th or 10^th century, probably as a roman look out post. Its situation is easily seen from afar catching the light up on the hill. Its position and strategic location explains the importance placed on the fort during the Middle Ages when in the ownership of the Viscounts of Narbonne. The chapel is mentioned in 978.

In the second half of the 15^th century the Chateau of St Pierre des Clars became sovereign property. In 1477, Louis XI bequeathed it to his first doctor, Claude de Moulins, for services rendered.

It remained in his possession until 1493.

In the second half of the 16^th century during the religious wars in the south of France the city of Narbonne was given the order to dismantle St Pierre des Clars and raise the fortifications to the ground. And in 1575, the main building was brought down removing the threat to Narbonne’s security.

The families de Neveys, de Calvisson, de Biord owned the Chateau, its buildings, shepherd’s dwellings and pastures until 1757. The lord of Montredon took over the lands belonging to St Pierre until they were confiscated in 1804.
