Château-Neuf et Vieux-Château

Château-Neuf and Vieux-Château are the medieval castle ruins of the Counts of Saint-Pol, set on a hilltop in Saint-Pol-sur-Ternoise in France's Hauts-de-France region. The old stronghold's grounds are now a public park where fortification remains sit alongside walking paths and family-friendly attractions.

Where did this castle come from?

The stronghold dates back to the first half of the 11th century, founded by Roger, the first Count of Saint-Pol — the oldest surviving reference to it appears in a charter from that same century. An original timber tower gave way to a square stone keep in the early 12th century, and in the decades that followed, under Count Hugues V, a round tower topped with a lead roof was added. By the mid-13th century the entire town had been enclosed within defensive walls, a sign of how central Saint-Pol had become to the counts' regional power.

The complex was split into two parts: Vieux-Château, the lower bailey used for storage and stables, and Château-Neuf, the counts' actual residence, ringed by towers, chapels and living quarters. Over the centuries the site received notable visitors, among them the French king Louis XI and several Burgundian dukes — a reminder of how significant Saint-Pol once was on the region's political map. The castle was destroyed for the last time in 1537 and was never rebuilt.

What can visitors see on site today?

Despite the destruction, the grounds still hold clear traces of the old stronghold. Visitors can find the defensive motte, rising roughly 30 metres above the surrounding plateau, the foundations of a 12th-century square tower about 12 metres wide, and the remains of the round tower with walls nearly 3 metres thick. The moat is still visible, along with two 13th-century chapels, Notre-Dame and Sainte-Catherine. The castle moat and the remaining vestiges of the old castle have been listed on France's supplementary inventory of historic monuments since 24 September 1979.

The park blends this history with recreation. Beyond the ruins, there are walking trails laid out along the natural contours of the land, a fitness trail, a vegetable maze, and a treetop rope course called "La tête dans les nuages." Younger children have their own ground-level obstacle course. In summer, the park also hosts open-air concerts and performances.

How to get there and when to visit?

The park sits on Rue du Mont in Saint-Pol-sur-Ternoise, in an easily accessible part of town. Through the summer it's open daily from early morning to early evening, which leaves room for either a quiet morning walk among the ruins or a relaxed family afternoon outdoors. Anyone wanting more historical depth can book a one-hour guided tour covering the castle's past and local legends — available for groups of five or more by advance reservation.

Given the uneven terrain — the motte, embankments and sloped paths — comfortable footwear is worth packing. The park draws both history enthusiasts interested in medieval fortifications and families looking for an active outdoor outing close to the town centre.
