Passel offers several distinct points of interest for a trip: archaeological traces, church architecture, places of remembrance, and a named walking and mountain biking route. On Mont-Renaud, a striking landform meets evidence of the past.
Archaeology and Architectural History
A monumental Neolithic enclosure was discovered at Le Vivier in Passel. The archaeological site was exceptionally well preserved. This reaches back to the Neolithic period, setting it apart clearly from the architectural remains of later centuries.
Today, only the lower parts of the entrance portal remain of the former Carthusian monastery of Saint-Louis, also known as Abbaye du Mont-Renaud. The ruins of a chapel built in the 19th century also remain on Mont-Renaud; elements from the 16th century were reused in its construction. The two architectural remains tell different stories: for the portal, the surviving lower sections are the focus, while the chapel combines a later building period with reused elements from an earlier period.
The parish church of Saint-Martin in Passel was rebuilt after 1918 and retains part of the façade of the earlier building, which was constructed in the second half of the 16th century. The relationship between the rebuilding and the earlier façade is a different aspect of architectural history from that of the chapel, whose construction incorporated elements from an earlier century.
Places of Remembrance and Landscape
A plaque on Mont-Renaud commemorates the fighting by the 57th Infantry Regiment from March 25 to April 13, 1918, and the fact that it blocked the enemy’s route to Paris. The Fontaine-Monument aux morts on Rue du Moulin was donated by Henry de Boulancy, the commune’s mayor. Passel therefore has both a military commemoration tied to specific dates and a monument whose donor is named.
Mont-Renaud is a hill separated from the Noyonnais uplands that rises prominently above the surrounding region. The Moyenne Vallée de l’Oise bird sanctuary, a Natura 2000 site, lies in the southeast of the commune. Before undertaking any specific projects within the protected area, please check its protection status.
Routes and Planning Your Time
The 10.5-kilometre Le Mont-Hubert walking and mountain biking route passes through Passel. The route takes approximately 2 hours and 20 minutes on foot and 45 minutes by mountain bike; the cumulative elevation gain is 153 metres. The comparison of journey times makes the mode of transport an important planning consideration, while the stated elevation gain provides further guidance about the route.
A map extract shows the GR225 long-distance trail alongside Passel. The map, dated June 2025, marks the Trans’Oise as the current route; Passel is also named in the extract. Check the route in connection with the works on the Canal Seine-Nord Europe before planning a specific trip.
