An old fortress from the 13th century. A nice park, but other than that there is not much to see.

Fort Risban dates from the end of the 16th century and was built on the site of an English tower: the Tour de Lancastre (Tower of Lancaster). The tower served to defend the harbor entrance. After an explosion in 1800, which caused serious damage to the building, major work was carried out in the first half of the 19th century. The fort was then restored and expanded. In 1921 it was declassified and purchased by the city in 1938. Fort Risban is on the list of protected buildings. Restoration work was started a few years ago.

The castle has been preserved in its original plans. It was built in the Middle Ages (13th and 15th centuries). It is an example of a fortified castle from the plains of Northern Europe. A walk along the “Moats” and an interior visit to the chapel, the vaulted cellars and the floors of the keep are recommended. Enjoy a distant past in the present.

A unique architectural whole The citadel of Arras was never besieged, hence its nickname “the belle inutile”, and is a well-preserved witness of the military buildings of the 17th century.

The castles in Pas-de-Calais span a rich history, from medieval fortresses like the 13th-century Olhain Castle and the Bours Keep, to 17th-century military architecture such as the Arras Citadel, and even 18th and 19th-century classical châteaux like Château de Barly and the Neo-Gothic Hardelot Castle.
Yes, the region boasts diverse styles. Hardelot Castle stands out with its unique Neo-Tudor architecture, distinctly British for a French château. The Arras Citadel is a prime example of Vauban's 17th-century military engineering, while Château de Barly showcases elegant 18th-century classical design.
Many castles are situated in areas perfect for outdoor exploration. For instance, near coastal fortifications like Fort d'Ambleteuse, you can find various hiking routes. You can explore options like the 'Dunes de la Slack' or 'Sentier du Fartz' trails. For more details on hiking and gravel biking routes in the region, visit the Hiking in Pas-de-Calais guide or the Gravel biking in Pas-de-Calais guide.
Several castles in Pas-de-Calais are considered family-friendly. Highlights like Fort d'Ambleteuse, Hardelot Castle, and Olhain Castle are noted for being suitable for families, often offering engaging historical experiences and grounds to explore.
The castles are often set amidst beautiful natural landscapes. Hardelot Castle is surrounded by 44 hectares of marshland, including a picturesque lake. Olhain Castle is immersed in the Lawe river, with its moats creating a stunning reflection. Coastal forts like Fort d'Ambleteuse offer views of the sea and are sometimes surrounded by water at high tide.
While not as widely known as some others, the Citadel of Montreuil, a 16th-century royal citadel built on medieval foundations, is described as 'very worth seeing' by visitors. The Bours Keep is another impressive 14th-century stone fortress that offers a deep dive into medieval history.
The best time to visit the castles in Pas-de-Calais is generally during the spring and summer months (April to September). The weather is more favorable for exploring the grounds and outdoor areas, and many sites host cultural events, such as the Midsummer Festival at Hardelot Castle. Always check individual castle opening hours, as they may vary seasonally.
Yes, the Château de Boulogne-sur-Mer, built in the 13th century, has basements that reveal sections of Roman walls, indicating its deep historical roots and the continuous occupation of the site over millennia.
Visitors frequently appreciate the well-preserved historical architecture, the immersive experience of stepping back in time, and the picturesque settings. For example, Olhain Castle is praised for its impressive moated structure and mystical reflections, while the Arras Citadel is valued for its unique military history and green walking paths.
Absolutely. Hardelot Castle is a significant site for Franco-British relations, known as the 'Cultural Center of the Entente Cordiale.' Its restored interiors detail the intertwined history of the two nations, and its Neo-Tudor architecture reflects British influence. The castle also features an Elizabethan theatre.
Yes, the renowned military engineer Vauban designed several fortifications in the region. The Arras Citadel, a UNESCO World Heritage site, is an exceptionally well-preserved example of his 17th-century military architecture. Additionally, Fort d'Ambleteuse, the only remaining fort of seven that defended the coast of Boulogne, was also built by Vauban.
Yes, the Château de Cercamp in Frévent was originally a Cistercian abbey. Over its history, it has served various purposes, including a wool weaving factory and military headquarters. Today, visitors can explore the entire château and its extensive 33-hectare park, which is listed as a Historic Monument.
