In Saint-Illiers-Le-Bois, two travel questions are easy to distinguish: which historical and cultural details interest you, and how much time should a hike take? The château dates back to the 13th century, while the Église de la Sainte-Trinité dates from the 16th century. There are also wooded areas along the Chemin du Hallot and named hiking routes. This lets you choose whether to focus your trip on local history or on a hike with a clearly specified duration.

Manor House and Church: Different Historical Points of Reference

The Château de Saint-Illiers-le-Bois, also described as a seigneurial manor house, dates back to the 13th century. Another point of reference is the Église de la Sainte-Trinité, which dates from the 16th century. These different dates give the history of the village more than one historical anchor. The types of buildings also offer distinct points of interest: the seigneurial manor house on the one hand, and the church on the other.

The bell tower of the Église de la Sainte-Trinité is square and clad in slate. A cemetery surrounds the church, and a side chapel houses a reliquary containing the relics of Sainte Clémence. The details therefore range from the age of the church and the tower’s shape and material to a specific religious connection. If you are interested in architecture, the square shape and slate cladding are distinctive features. For a closer look at religious heritage, the reliquary in the side chapel is a point of interest in its own right.

Wooded Areas and Hiking Routes

The wooded areas along the Chemin du Hallot consist mainly of deciduous trees and provide a refuge for biodiversity. This adds a landscape dimension to the historic buildings: here, the focus is on the vegetation and its role as a refuge. You can therefore weigh cultural history and nature as different interests when planning your trip.

The official intermunicipal hiking route “De gare en gare – Bréval à Bonnières-sur-Seine” passes through Saint-Illiers-le-Bois. The municipal tourism information about it dates from 2023; check the route before setting out. The title “De gare en gare à travers les champs,” which also begins with “De gare en gare,” refers to a circular route. The 2023 edition of the leaflet lists its length as 19 km, its duration as five hours, its difficulty as moderate, and its elevation gain as 135 m. Later editions may contain different route information.

The similar route names can be distinguished by their descriptions: the intermunicipal route is described as passing through Saint-Illiers-le-Bois, while the circular route has a stated length, walking time, difficulty level and elevation gain. The five hours provide a specific time frame for this circular route. The moderate difficulty and elevation gain add further information about the hike. You can use the route description and the time available to plan your hike.
