Yzengremer: Château, Industry and Hiking

Yzengremer lies in the southwest of the Vimeu Plateau, about seven kilometres from the coast. The village combines architectural history and industrial heritage with a hiking route through the countryside and views over the Bresle Valley.

Hiking and directions

The route description, updated on 2 October 2025, lists the “Yzengremer plateau et vallée Bresle” route as a moderate 10.5-kilometre hike, with an estimated duration of 3 hours and 20 minutes. It starts at the Place de la Mairie in Yzengremer and returns to the car park in the village centre. Mostly grassy paths cross the countryside and offer views over the Bresle Valley.

Two departmental roads cross the village: the R.D. 19 between Béthencourt-sur-Mer and Dargnies, and the R.D. 402 between Méneslies and Woincourt. Their respective endpoints help distinguish the two routes through the village.

Château and protected heritage

The Château d’Yzengremer stands in the centre of the commune, southwest of the public square. A tree-lined path leads from there to the château. It was rebuilt after 1635 and restored in the late 19th century. Its architectural history therefore includes both a rebuilding and a later restoration.

By decree of 12 November 2018, the château, its dovecote, the courtyard and garden area, the approach avenue and the well were granted protected status. The modern outbuildings are excluded; the protection applies to cadastral parcels AE 86 to 91. The scope therefore extends beyond the main building to include named outdoor areas and other features of the estate.

The Church of Saint-Médard is also a point of interest for local history: it contains six protected objects, including a reliquary. The château represents architectural and garden history, while the church offers insight into protected movable heritage.

Industrial history across different periods

The Dehesdin iron foundry is no longer in operation. Its expansions can be traced through three dates: annealing furnaces were added in 1897, storage rooms in 1899 and a polishing workshop in 1901. The expansion therefore spanned several years and involved different areas of the business.

The Robert Couillet locksmithing factory is still operating under the same name; its main building was erected in 1890. The dates thus contrast a main building from 1890 with the later expansions of the Dehesdin foundry between 1897 and 1901. These are distinct industrial histories and operating statuses to discover in Yzengremer.

Plan your stay

If you are looking for a hotel in Yzengremer, the focus of your planned stay can help you find your way around: the hike, with an estimated duration of 3 hours and 20 minutes, is a defined block of time; the village’s history is spread across the château, church and industry.
