The old citadel of Serres

On the rock of Pignolette, overlooking the city, stood a castle, from the tenth century. Around 1580, Lesdiguières transformed it into a citadel and made it the seat of a Protestant garrison. In 1633, it was destroyed by the monarchy to better control the region, against possible revolts. The walls are still clearly visible. In the center of the west rampart, the Auche door, gave access to gardens, vineyards and cultivated land.
