From the village of La Montagne, the Sentier de la Montagne offers a panorama over the Authie Valley. Together with a second, longer route, it gives hikers two concrete, comparable profiles in terms of time and distance. River landscapes, an old Roman road and the church add geographical and historical details to the focus on hiking.
Hiking: comparing two routes
The Sentier de la Montagne starts at the town hall in Thièvres, in the Pas-de-Calais département. It is 9 km long, takes 2 hours and 15 minutes, and is marked in yellow. At the village of La Montagne, the path offers a panorama over the Authie Valley. This combines a hike with a stated distance and duration with a specific viewpoint along the way.
The “Autour du Prieuré Authie-Thièvres” route starts at the Prieuré d’Authie. It is 10 km long and takes between 2 hours 30 minutes and 3 hours. This makes it 1 km longer than the Sentier, and its time range is 15 to 45 minutes longer. The starting points also differ: the Sentier starts at the town hall, while the second route starts at the Prieuré d’Authie. Check local conditions before setting out on either route.
Waterways around Thièvres
The Kilienne, also known as the Quilienne, flows into the Authie at Thièvres. The Marais de Thièvres is bounded by the Ruisseau Saint-Pierre to the north and the Authie to the south. The variant name Quilienne refers to the same watercourse as Kilienne; the Authie is both the destination of this tributary and the southern boundary of the Marais. These relationships help distinguish the waterways mentioned.
Roman road and local history
The D1, which marks the boundary, is an old Roman road called the Chaussée Brunehaut. This historic route connected Nemetacum, present-day Arras, with Samarobriva, present-day Amiens. The old and modern place names offer two points of reference in time: the route is associated with the ancient names Nemetacum and Samarobriva, while Arras and Amiens are their modern-day equivalents. Thus, in addition to being a road name, the Chaussée Brunehaut has historical significance extending beyond Thièvres.
The church and the Moulin de Thièvres
The church in Thièvres was rebuilt in 1875. Built of brick in the Neo-Gothic style, it is dedicated to Saint Pierre. These features describe different aspects of the building: the date refers to its reconstruction, the brick to its building material, the Neo-Gothic style to its architecture, and Saint Pierre to its dedication. Together, these details offer a concise insight into the town’s architectural and church history.
The Moulin de Thièvres is also linked to the Authie: it is considered a cultural and historical treasure and lies 8 km downstream from the source of the Authie. The river is therefore not only part of the landscape description; it also plays a role in understanding a local heritage site. Those exploring Thièvres through its historical themes will encounter a variety of points of interest: an old long-distance route, the architectural history of the church, and a mill heritage linked to the Authie.
