By excavations in 1954 mister Fourny found a bronze piece that was made in Trier during the reign of Constantine The Great (307-337). This discovery shows that this cape was already inhabited in very early times. In the 12th century the castle played an important part in the defense and development of trade. It was strategically placed along the trade route to Lombardy of English wool. The castle was inhabited until 1780. The French conquered the castle on August 10th, 1681.

The ruins are situated in the middle of the charming town of La Roche. You cannot miss it. Visiting the castle is a must when you are paying this touristy village a visit.
