It is situated on a ridge, overlooking valleys to the north and south, in the heart of the village of St-Ferriol, near the towns of Quillan and Esperaza.

The castle features six monumental fireplaces and another on the top floor decorated with a coat of arms, a mention of " Noble Anne de Mauleon " and the date 1630.

The Château de Saint-Ferriol used the latest military techniques of the period, notably bastions placed at the four corners of a rectangular building enclosing an inner court.

These bastions are furnished with gun ports (cannoniers) to provide covering fire to all external walls.

The castle is now undergoing a long programme of restoration, the objective being to return it, as far as possible, to its state in around 1600, using original materials and techniques.

Local records were lost in a fire in the early eighteenth century, and whatever remained seems to have been deliberately destroyed during the French Revolution.

The few remaining records and architectural clues, a reasonably good outline of the history of the seigneurie, village and Château de Saint-Ferriol.

Some buildings existed on the present site before 1300, but the principal castle at that period was some distance away along a ridge called Le Dent.
