Le Quiou brings together medieval and more recent architectural history, Roman archaeology and a distinctive limestone landscape. Château de Hac dates from 1440 to 1448, while the parish church of Notre-Dame dates to the mid-19th century. The area also features the Roman villa and the Espace naturel sensible de la Hazardière. This gives you a choice between taking a closer look at architecture and history, or enjoying a stay focused on nature and trails.
Architectural history and special details
Château de Hac was built between 1440 and 1448 for Jean Hingant, chamberlain to the Duke of Brittany. It is made almost entirely of Faluns limestone. This brings together a clearly defined historical period and a distinctive material in a single building. If you are interested in the history of the château, its patron is also part of the story: Jean Hingant held a court office under the Duke of Brittany. The limestone also offers a connection to the area's geological history.
The parish church of Notre-Dame was built between 1864 and 1866 in the Neo-Gothic style. Its floor plan is in the shape of a Latin cross. Inside is a 15th-century credence table reused from the former church. Other details are recorded at the Chapelle du Haut-Tréveleuc: a credence table set into the wall, with painted Renaissance geometric motifs, and a portal with an archivolt decorated with quillons. There is also the coat of arms of the Plumaugat family, the lords who founded the settlement in 1583. The two credence-table details offer different points of interest: at Notre-Dame, it is the reuse of an element from an earlier church; at the chapel, it is the combination of wall decoration and Renaissance motifs.
Roman archaeology in Le Quiou
The Villa Gallo-Romaine du Quiou was inhabited from the 1st to the 4th century and is one of the major ancient archaeological sites in the Côtes-d’Armor department. Its long period of habitation gives the archaeological site a different timescale from the buildings of Château de Hac or the parish church. Guided tours with commentary are available at the villa, making its archaeology accessible to visitors. If you would like to focus on this, check the tour dates in advance.
Limestone landscape and trails
The Espace naturel sensible de la Hazardière is open to the public. Its limestone bedrock is unique in Brittany. Fifteen million years ago, the Faluns Sea covered this area. This geological feature gives the natural area a distinct focus alongside the architectural and archaeological sites: in Le Quiou, discoveries include not only historical periods but also the area's distant landscape history.
A circular walking route connects the Espace naturel sensible de la Hazardière with the local Voie Verte. The history of a former railway line is another point of reference: it served Le Quiou and was converted into a Voie Verte. This former line forms part of the V3 (Saint-Malo–Rhuys). A local walking loop and a larger cycling and greenway connection thus offer different ways to explore the area. No route distances or walking times are provided, so choose according to your interest in the natural area, the railway's history or both, without planning for a specific duration.
The Chapelle du Haut-Tréveleuc has specific visiting conditions: it can be visited during the Journées du patrimoine or by prior arrangement with the owners. Confirm the arrangements or the dates of the event period before your visit. This allows you to include the chapel in your cultural itinerary without assuming that it is open at all times.
