Pont Cornuel

Pont Cornuel, in Bouray-sur-Juine, is a stone road bridge spanning the Juine river on the boundary between the communes of Bouray-sur-Juine and Lardy, in the Essonne department of the Île-de-France region. Also known locally as Pont de Cochet, it still carries road traffic today and remains one of the most recognisable landmarks along the Juine valley.

Where does the bridge's name come from?

The bridge takes its name from the Cornuel family, who owned the nearby Mesnil-Voysin estate before it passed to chancellor Voysin. The family's name was attached to the crossing long before the structure took its current form, since the estate later changed hands several times. The alternative local name, Pont de Cochet, most likely refers to the immediate surroundings of the crossing rather than to a separate structure.

When was the current bridge built, and who designed it?

The bridge standing today dates from the mid-18th century, with construction commonly placed around 1757. The project was commissioned by the Marquis de Broglie, who had architect Boullanger design and build a new crossing. Notably, the bridge was built on dry ground at a new location slightly north of the original crossing point — only after the structure was completed was the course of the Juine diverted to flow beneath it. This sequencing avoided the technical difficulties of laying foundations directly in an active riverbed, a practical solution for 18th-century engineers working in a relatively narrow valley.

What does the bridge look like, and how is it built?

Pont Cornuel is a single-arch stone bridge, built with a distinctive basket-handle arch (anse de panier) — a flattened, elliptical arch profile widely used in French bridge-building of the period. This shape allowed the structure to keep a lower rise while still spanning the necessary width, a solution that was both practical and visually elegant for crossing the Juine's relatively compact valley. The bridge continues to serve as a functioning road crossing, and its solid masonry silhouette blends naturally into the surrounding river landscape.

Why is the bridge protected, and what else is there to see nearby?

Pont Cornuel was listed as a monument historique on 6 May 1980, an official recognition of its architectural and historical significance for the region. The bridge sits within the area covered by the Gâtinais Français Regional Nature Park, which protects the Juine valley and its surrounding countryside. Bouray-sur-Juine itself has a marked heritage discovery trail that highlights local landmarks, with the bridge serving as one of its natural waypoints alongside other river-related structures. The area is well suited to walks along the Juine and short cycling routes connecting Bouray-sur-Juine with neighbouring Lardy.
