Discover Oust-Marest

Oust-Marest combines designated walking trails with evidence of its architectural and industrial history. If you are looking for a hotel for a stay in the town, these themes may shape your plans: you may be particularly interested in trails towards the Bresle Valley, the Église Saint-Martin or the historic buildings. The local trails and sights offer different ways to explore these themes.

Trails in and towards the Bresle Valley

The GR de Pays en Vallée de Bresle passes through the Oust-Marest area and runs from Aumale to Le Tréport. A planning document from 2021 lists this route in connection with Oust-Marest’s walking trails. Check trail conditions before setting out. The Chemin entre Verre et Mer is also described in a planning document from 2021: it is about 15 kilometres long and designated for pedestrians, mountain bikers and horse riders. This trail is therefore notable for its approximate length and several named user groups, while the GR route connects the towns of Aumale and Le Tréport.

Several walking trails have been designated in the Oust-Marest area to help visitors discover the town and its architectural heritage. Walking trails also provide environmentally friendly routes towards the Bresle Valley. If you are planning a walk, check trail conditions and signage before setting out.

The Église Saint-Martin and its furnishings

The Église Saint-Martin is a building dating from the 13th to the 16th century. The church contains a 13th-century tomb slab, a 16th-century Entombment and a 15th-century Christ on the Cross. The engraved figure of Raoul d’Aoust appears on the tomb slab; he died in 1269. The different dates give each work its own historical context, while together they form part of the church’s furnishings.

Access is important when planning a visit: the Église Saint-Martin is closed, but can be opened on request. Check the arrangements for visiting before you arrive. This allows you to include the church in your plans without assuming it has regular opening hours.

Workers’ housing estate and regional architecture

Oust-Marest has a former workers’ housing estate with rows of houses arranged perpendicular to the main road. The orientation of the houses makes the layout of the ensemble clear. The estate also recalls industrial activity in the locksmithing sector and the expansion of Société Fichet since the end of the 19th century. The former residential buildings can therefore also be viewed in the context of local industrial history.

Another example of the built heritage is the ensemble comprising the town hall and school, the Mairie-Ecole. It is a historic building made from materials typical of the region. Together with the former workers’ housing estate, it illustrates two different aspects of local architecture: on the one hand, the public building comprising the town hall and school, and on the other, the residential buildings arranged in rows. Visitors interested in architectural styles can take both themes into account when planning their stay, without reducing them to the same historical function.

The Bresle in its wider natural context

The Bresle is a Category 1 river and is home to populations of Atlantic salmon (Salmo salar). An environmental inventory dated 16 January 2025 describes these aspects in the wider context of the Vallée de la Bresle Natura 2000 site. This natural theme adds a perspective on the valley to the town’s architectural and industrial history. The trails towards the Bresle Valley and the nature information can be considered separately when choosing what to focus on: one concerns walks and architectural heritage, the other the river and its fish populations.
