Three Doms Circuit (Loop A)

The Santerre plateau, rich in crops, is cut through by the picturesque valleys of the Avre and Trois-Doms. This land was nicknamed the "Red Zone" because it was deeply affected during the First World War. The "potato propagator" Parmentier was born here.
At the start, Montdidier, perched on its hill, is located on the Trois-Doms valley. Before leaving, you can admire the town hall rebuilt in Flemish style and the faithfully restored flamboyant Saint-Sépulcre church. Leave the town by following the Trois-Doms valley to reach Courtemanche, Framicourt, Marestmontiers, then Bouillancourt-la-Bataille. You are still in the picturesque site of the Trois-Doms river; here the rebuilt church has classified baptismal fonts. Head towards Hargicourt (D483), cross the commune via the small Brache valley, join the eponymous village loved by fishermen and hunters, cross the railway (D256), pass in front of the Saint-Antoine chapel to reach La Neuville-Sire-Bernard. At the crossroads, go straight ahead, climb to the Santerre plateau (D137) via Le Plessier-Rozainvillers, take Hangest-en-Santerre (D54), a flowery village, then head to Davenescourt (D41), a very hilly site that has a castle with a large park and a chapel from 1762; in the village there is a beautiful flamboyant church with a very rich interior. Leave the village, you need to pedal hard (D160) to reach Warsy. By a small road on the right, you descend into the Avre valley, on the right bank admire a white stone castle (1725) and an old washhouse. Resume your route and reach Guerbigny, still in the Avre valley, surrounded by woods and ponds admire the church from the 12th and 15th centuries. Leave the locality not without making an effort (D135E) for Lignières, Etelfay before returning to Montdidier passing in front of a German military cemetery, reach the town center passing in front of the Parmentier statue in the square that bears his name. Not far away, Saint-Pierre church and the Priory with an orientation table allow discovery of the panorama over the Trois-Doms valley, the lower town, and the countryside.
