Le Tanu brings together natural and cultural heritage in different forms: La vallée de l’Airou leads from Champrépus towards Le Tanu, while Église Notre-Dame du Tanu, Viaduc du Guibel and Bois Frou each reveal their own architectural and local history. When planning your trip, it is helpful to distinguish the specific walking route from the cultural highlights.

Hiking on La vallée de l’Airou

The La vallée de l’Airou walk is rated easy, is 11.5 kilometres long and takes around three hours. The yellow-marked circular route starts and ends at the church car park in Champrépus. It heads from Champrépus towards Le Tanu and follows the two local rivers, the Douquette and the Airou. The direction is important for planning: Champrépus is the stated starting and finishing point, while Le Tanu indicates the direction of the route. The easy rating and approximate duration answer different planning questions: easy describes the level of difficulty, while around three hours indicates how long it takes. Together with the 11.5-kilometre distance, this gives a more precise picture than the word “easy” alone.

The Romanesque Église Notre-Dame du Tanu

Église Notre-Dame du Tanu is open to visitors; contact the municipal administration to arrange access. This Romanesque church has an apsidal semi-dome and a portal dating from the 11th or 12th century. Inside, there is a massive oak pulpit featuring the four Evangelists in bas-relief. You can appreciate different aspects of the building: its Romanesque design, historic portal and the pulpit’s carved decoration. During your visit, you can shift your attention between the architecture and the reliefs.

Viaduc du Guibel: railway construction and dimensions

Viaduc du Guibel was built in 1869 for the Paris–Granville railway line and spans the Airou Valley. It is 98.5 metres long and 22.5 metres high. The two measurements describe different dimensions of the structure: its length shows its overall span, while its height provides another measure above the valley. Along with the year it was built, these details make it possible to consider the viaduct both as a railway structure and in terms of its construction. There are accessible picnic tables on site; check their availability before your visit.

Bois Frou: family and religious order history

The former residence at Bois Frou was the manor of the Sainte-Marie family until the middle of the 17th century. The Dominicans, who had been based in Mesnil-Garnier since 1620, settled at Bois Frou towards the end of the 17th century. The chapel at Bois Frou was destroyed during the French Revolution. The dates mark different stages: 1620 refers to the establishment in Mesnil-Garnier; the move to Bois Frou came only towards the end of the 17th century. The history of Bois Frou thus adds family and religious order history to the story of the church and viaduct.
