Castle of Dieppe

The Castle of Dieppe is situated on a terrace approximately 30 meters above sea level, perched on the Caude-Côte cliff, offering commanding views over the town and the English Channel coast. The structure is organized around an irregularly shaped quadrilateral courtyard, once enclosed by four towers at each corner. Of these, three round towers survive today, while the fourth, likely square in plan and located on the east side, no longer remains.

Dominating the complex is the large west tower, or keep, constructed around 1360. This cylindrical tower measures about 11 meters in diameter and has walls two meters thick, designed for defense. Its features include narrow vertical openings called arrow slits or “archères,” which allowed archers to fire while remaining protected. This tower was connected to the defensive walls that encircled the town, integrating the castle within Dieppe’s broader fortifications.

The castle’s perimeter walls showcase a distinct construction technique, built in alternating horizontal layers of flint, sandstone, and brick. Portions of the walls were topped with machicolations—stone openings used to drop defensive materials—and a covered walkway known as a “chemin de ronde,” enabling soldiers to patrol safely along the battlements.

Two drawbridges secured the main gates: one at the “porte des champs,” controlling access from the countryside, and the other situated facing the town. These drawbridges could be raised to prevent enemy entry.

To the south of the medieval castle lies a 17th-century citadel, fashioned as a semicircular defensive boulevard with a fortified esplanade. This citadel incorporates remnants of the 14th-century tower of Saint-Rémy church, which was absorbed into the later fortifications. Additional defensive features include a barbican—a fortified outwork—guarding the southeast façade, and a detached tower connected to the main walls, further strengthening the castle’s perimeter.

Inside, some rooms retain elegant gilded wood paneling, reflecting the castle’s later use as a residence and administrative center. Surrounding the castle were deep moats filled with water, serving as a barrier to attackers. Essential military infrastructure remains evident, such as rainwater cisterns, wood-fired kitchens, and secure storage spaces for arms and munitions.

A barracks building, constructed in 1630 on the southwest side of the castle, symbolizes the site’s shift toward housing troops. Today, this building serves as a temporary exhibition space within the museum complex.

During the Second World War, the castle’s defenses were strengthened with new walls and bunkers, known as blockhaus, as part of the German Atlantic Wall coastal defense system. These additions represent the castle’s continued military relevance well into the 20th century.

Together, these features provide an extensive record of Dieppe’s evolving strategic, military, and residential functions through the centuries, preserved in a site that overlooks the town and surrounding coast to this day.
