Église Saint-Frambourg (Senlis) walks

Former capital of the Sylvanectes Gauls, Senlis was known as Augustomagus in the 1st century, during the reign of the Roman Emperor Claudius. From the 3rd century onwards, thanks to its walls, the Gallo-Roman enclosure of Senlis was one of the best-preserved in northern Gaul. The date of construction has still not been determined. What remains certain, as was already established in the 19th century, is that the fortifications were built after the passage of the Germanic hordes in 275–276, and after the year 278, withstanding the barbarian invasions and later the Norman raids. Senlis boasts a history spanning ten centuries of virtually uninterrupted royal presence. The town was the site of a Merovingian and later Carolingian castle or palace from the early Middle Ages onwards; although it has completely disappeared and there is no definitive archaeological evidence, it is mentioned in numerous ancient deeds and documents.

Eleventh stage of the Grand Tour of Île-de-France via the GR®11, connecting Chantilly-Gouvieux station to the village of Borest, reached by crossing the Chantilly estate, the Chantilly and Ermenonville forests, with a detour through the historic centre of Senlis and, optionally, a moment of reflection in front of the memorial to the victims of the March 1974 plane crash. The route follows, more or less closely, the Nonette River, which is crossed several times. The route for this stage is almost entirely in the forest, with little elevation gain, making it a very pleasant hike, and the crossings of Chantilly and Senlis add a rich touch of heritage. This stage requires an overnight stay to avoid laborious car manoeuvres. It is therefore the first of two consecutive stages, both entirely within the Oise department, between the Chantilly-Gouvieux and Crépy-en-Valois railway stations.
