Château de Boves

Boves Castle (Château de Boves) sits in the village of Boves, roughly 8 km southeast of Amiens, in the Somme department of the Hauts-de-France region.

What actually survives on site?

Two things remain of the once-large complex: an artificial castle mound (motte castrale) and two wall sections of a 14th-century tower, the last major rebuilding phase the castle went through. The mound itself was raised, most likely in the 10th century, entirely by hand rather than shaped from a natural hill, and was enlarged more than once over the following centuries to carry timber and stone defensive structures.

How long was the site occupied?

Continuously from the 9th century through the 17th, Boves served as a major aristocratic residence and a genuine center of regional power in Picardy. A priory dedicated to Saint-Ausbert, affiliated with the abbey of Cluny, operated inside the castle courtyard during the 12th century. Ferry I of Vaudémont rebuilt the fortress in the 14th century — the tower walls still standing today date from that campaign. The castle was dismantled in 1595, and its stone was later carted off and reused, effectively turning the site into a quarry.

Why does this ruin matter historically?

In July 1185, the Treaty of Boves was signed here between King Philip II Augustus of France and Philip of Alsace, Count of Flanders, settling a dispute over territory and influence in northern France. It's one of the more consequential medieval agreements sealed on French soil, which is why Boves comes up in general histories of the period and not only in local ones.

What have archaeologists found?

Excavations carried out on the motte between 1996 and 2019 traced an uninterrupted, layered sequence of construction phases running from the 9th to the 17th century. The dig is ongoing, and the site is still treated as an active archaeological zone rather than a finished monument.

How do you get there, and what should you know before visiting?

Boves is a short drive southeast of central Amiens, easily reached by car. Entry to the ruins is free, but this is a working excavation site: stick to the marked paths, don't climb on the old walls, and watch your footing — loose stones and uneven ground are a real hazard. Guided tours led by the archaeologists working on the dig are organized periodically, including through Amiens Tourisme, and there's also a roughly 8 km archaeological walking trail rated medium difficulty, for which booking ahead is recommended.

When's the best time to go?

The ruins are open year-round, but the ground is uneven and there's no shelter, so drier weather — spring or summer — makes for easier, safer footing. If you want to join a guided visit, check the schedule in advance, since these run on set dates rather than continuously.
