In Crehen, the story stretches from a Neolithic burial site to a surviving monastery building dating from the mid-17th century. In between are ecclesiastical history, paths along a former railway line and landscapes along the Arguenon. When planning your trip, you can give these themes whatever weight best suits your interests.

From the Neolithic to Monastic History

The Allée couverte de la Ville Génouhan dates from the Neolithic period, given here as spanning 5,800 to 2,500 BC. The structure is a 12.70-metre-long collective burial site and is considered one of the most important dolmens in the eastern part of the Côtes-d’Armor department. It therefore predates the town’s medieval and ecclesiastical traces by a considerable margin.

The Manoir dit château de la Touche-à-la-Vache includes the remains of a 15th-century keep. By decree dated 27 February 1926, it was added to the supplementary inventory of historic monuments. The property is privately owned and is now used as a farm. These details place the manor in its historical context and indicate its current status.

Religious sites also tell of different periods. The church of Saint-Pierre de Cherehen was first mentioned in 1163, when it belonged to Saint-Jacut Abbey. The former Carmelite monastery of Le Guildo replaced a collegiate church founded by Charles de Dinan in the early 15th century. It served to house and support poor people and pilgrims. One building from the mid-17th century survives from the monastery.

The Château du Guildo is also listed as a historic monument. Admission is free year-round; check local conditions before your visit. This makes the château a distinct part of your trip planning, while the history of the manor, church and monastery offers further points of reference across time.

Walking Trail and Landscapes Along the Arguenon

A walking trail between Crehen and Le Guildo follows the former railway line. In 1991, one section was named “Allée Kilmore-Quay” to mark the municipality’s twinning with an Irish fishing village. The name commemorates this municipal connection and also recalls the history of the trail. Check local trail conditions before setting out.

The “Autour de l’Arguenon maritime” route is associated with the Arguenon estuary, green corners and historic heritage. Another landscape highlight is the Domaine du Château du Guildo in Crehen: this 5.36-hectare Natura 2000 site includes coastal woodland, dunes, salt marshes and mudflats. These landscape types give a clear sense of the range of natural features, from wooded areas to open coastal land.

The highlights are easy to distinguish when planning your visit: the covered alley represents the area’s archaeological period, while the manor, church and former monastery offer different chapters of regional history. The route and Natura 2000 site put more emphasis on landscapes and walking trails. This distinction can help you choose what to explore in Crehen based on the themes that matter most to you on your trip.
