Mareil-sur-Mauldre: Bridge, Church and Historic Washhouses

Mareil-sur-Mauldre can be explored through two specific focal points: historic buildings with clearly dated details and the Mauldre river landscape. If you are planning a hotel stay in Mareil-sur-Mauldre, these subjects can give your trip a fitting focus. The townscape includes a bridge listed as a Monument historique, the parish church of Église Saint-Martin and two historic washhouses; the river and hiking routes offer a different perspective on the town.

Historic Buildings and Their Dates

The Pont sur la Mauldre has been listed as a Monument historique since 23 July 1937 and has two arches. Construction work lasted from April to December 1778. These are two distinct dates: the construction period describes the work on the structure, while the later listing marks the beginning of its protected status.

The parish church of Église Saint-Martin is listed in the supplementary inventory of Monuments historiques. Inside are a 15th-century Pietà and 17th-century wall frescoes. These dates can be compared with those of the bridge and the washhouses: they span the Pietà, the frescoes and bridge work, through to the 19th-century buildings.

The washhouses also each have their own location and dates. The washhouse near Vallée Renault was completed in late summer 1876. It has two large basins; its overall dimensions are given as 7.6 m × 4.0 m × 0.6 m. A second public washhouse was built in 1885 in the town center, at the beginning of Rue des Fontaines. Thus, two washhouse buildings dating from different periods stand side by side in the record: one near Vallée Renault and one at the start of Rue des Fontaines.

The timeline runs from the 15th-century Pietà, through the 17th-century frescoes and the 1778 bridge works, to the completion of one washhouse in 1876 and the construction of the second in 1885. By contrast, the bridge’s listing in 1937 relates to its protected status, not its construction date.

The Mauldre and Two Hiking Routes

Near Mareil-sur-Mauldre, the Mauldre becomes wider and deeper after joining the Ru de Gally and the smaller Petit Ru de Riche. As far as Épône, the river forms meanders and flows into the Seine there. The first statement describes the change after the two tributaries join near Mareil; the meanders and confluence refer to the river’s further course as far as Épône.

Two hiking routes offer different highlights. The “Autour de Mareil-sur-Mauldre” loop first follows the railway line and then the Ru de Gally as far as the Maladrerie. The hike from Mareil-sur-Mauldre to Épône, by contrast, connects the two railway stations and follows the Mauldre through the countryside. The main differences to consider when choosing a route are its format and described course: a loop with sections along the railway line and the Ru de Gally, or a route linking two stations along the river. Check local conditions before setting out.
