Explore Oust-Marest through its walking trails, architectural history and traces of its former industry. Several signposted routes offer a way to discover the village and its architectural heritage. Other highlights include the town hall and school complex, a former workers’ housing estate, and the Église Saint-Martin, with features dating from several centuries. These topics offer different perspectives: you can take walking routes, historic architecture and a visit to the church into account when planning your trip.
Walking Trails and Routes
The 2021 planning document mentions the GR de Pays en Vallée de Bresle and the Chemin entre Verre et Mer. The GR passes through the Oust-Marest area and runs from Aumale to Le Tréport. The Chemin is about 15 kilometres long and designated for walkers, mountain bikers and horse riders. The information offers different points of reference: for the GR, it names the route through the area and its endpoints; for the Chemin, it gives the approximate length and the groups of users. Several walking trails are also signposted to help visitors discover the village and its architectural heritage. They provide environmentally friendly connections towards the Bresle Valley. Before setting out, check route conditions and, for the signposted walking trails, the signage too, as it may change.
Church and Architectural History
The Église Saint-Martin is a building dating from the 13th to the 16th century. It contains a 13th-century tombstone bearing an engraved depiction of Raoul d’Aoust, who died in 1269. There is also a 16th-century Entombment and a 15th-century Christ on the Cross. The construction period and individual works thus span several centuries of sacred history. It is important to make arrangements before your visit: the church is closed but can be opened on request. Confirm your visit again before travelling.
Other buildings also give the village’s history architectural form. The Mairie-Ecole complex, comprising the town hall and school, is a historic building made from materials typical of the region. The former workers’ housing estate is characterised by rows of houses arranged perpendicular to the main road. It bears witness to industrial activity in the locksmithing sector and to the expansion of the Société Fichet since the end of the 19th century. The two present distinct architectural themes: a public complex made from materials typical of the region, and a housing estate whose layout and history are linked to industry.
The Bresle in the Wider Natural Landscape
In the wider context of the Vallée de la Bresle Natura 2000 site, an environmental inventory dated 16 January 2025 describes the Bresle as a first-category river with populations of Atlantic salmon (Salmo salar). This ecological perspective adds the wider valley landscape to the local architectural history; the walking trails and buildings, by contrast, focus on Oust-Marest itself.
