Duault: Hiking and Architectural History

When planning a trip to Duault, you can weigh up two specific interests: hiking the Circuit des Collines and exploring the architectural history of several historic sites. The route details help you estimate the time required for the hike; the buildings, meanwhile, are notable for their different construction phases, completion dates and states of preservation. This can help you decide whether outdoor activity or cultural history should play a greater role in your stay.

Hiking the Circuit des Collines

The Circuit des Collines, also known as Circuit 8, is 14 km long. The route description published in 2025 gives a total ascent of 255 m and a duration of 3 hours and 15 minutes. The trail starts at the car park by the Calvary of Kernaëret, on the road to Saint-Servais. The distance, elevation gain and stated duration provide three different measures to help you plan: the kilometres describe the route’s length, the elevation gain adds information about the terrain, and the duration helps you estimate how much time to allow in your day. It is a route estimate, not a personal walking time. The route offers impressive views of the countryside around Callac. If your choice depends not only on distance and time but also on the scenery, this is another factor to consider. Trail conditions can change; check them before setting out.

Chapels and architectural history

The Prieuré de Landugen is a priory dating from the 16th century. Its chapel has been partially listed as a Monument historique since 17 December 1926. At the Chapelle Saint-Jean in Landugen, the main construction phase dates to the third quarter of the 16th century; the nave and west façade were completed in 1559. These details describe different aspects: the listing of the Prieuré applies to its chapel, while Saint-Jean has a general construction phase associated with the completion year of two building elements. The year 1559 refers to the nave and west façade, not to the chapel as a whole. This distinction lets you separate a broader timeframe from specific dates for individual parts of the buildings.

Church and château in historical perspective

The history of the Église paroissiale Saint-Maudez also includes a change: the earlier church building dated from the 16th century and was destroyed. The Église paroissiale Saint-Maudez was completely rebuilt by Le Guerranic in 1892. The year 1892 therefore refers to the rebuilding, while the destroyed predecessor dates from the 16th century. At the Château de Rosviliou, the date applies to a specific section: the south wing was built in the second half of the 18th century. These three dates offer different perspectives on Duault’s architectural history—from a destroyed former church building and its later reconstruction to one part of the château. When planning your trip, you can consider church architecture and château architecture as separate themes.

The Allée couverte de Toul-an-Urs

Another historic site is the partially destroyed Allée couverte de Toul-an-Urs in Duault. It lies beneath a cairn, whose oval outline is still discernible. The structure is now 7 m long and was originally more than twice that length. Comparing its present and original lengths shows that only part of its former extent remains. Together with the still-visible oval outline, this describes both its current state and its original dimensions. This site differs from the chapels and churches: here, the focus is on its shape, dimensions and partial destruction, whereas the other buildings are dated primarily by their construction phases, completion dates or protected status.
