Pont sur la Cadoule

Pont sur la Cadoule, in the town of Castries in the Hérault department of Occitanie, is a small stone bridge spanning the Cadoule river. It looks unassuming at first glance, but it carries over two and a half centuries of history and the carved coats of arms of two bishops of Montpellier.

Where is the bridge and how do you get there?

The bridge stands on Rue Gaston Baissette, right in the heart of Castries, a village a short drive northeast of Montpellier. It's an easy stop for anyone exploring the village on foot: park near the centre and walk a few minutes down toward the riverbed. The Cadoule itself is a modest, seasonal stream that can run nearly dry in summer and swell considerably in winter, which explains the solidly built stone structure crossing it.

What does the bridge look like?

The bridge rests on a single span of 14.70 metres, eight metres wide and five metres high. Its vault follows the classic "anse de panier" (basket-handle) profile, and the whole structure is built from carefully dressed stone. A solid balustrade runs along the top on a moulded cornice, and the noticeable rise from the ends toward the centre gives the deck the humpbacked profile typical of bridges from that era. On both the upstream and downstream faces sit carved heraldic cartouches, the bridge's real signature and the detail that catches every visitor's eye.

What is the history behind it?

The structure is dated to the third quarter of the 18th century, with 1768 most commonly cited as the year of construction. The carved cartouches link the bridge to two figures tied to the diocese of Montpellier: Cardinal Pierre de Bonzy, who served as bishop of Montpellier and president of the Estates of Languedoc, and Raymond Durfort, the bishop in office at the time the bridge was built. Their standing explains why what was otherwise a working rural bridge received such a formal decorative treatment. Its historical and architectural value led to its listing as a monument historique by decree of 12 October 1946.

What else is worth seeing nearby?

Castries is best known for its monumental 17th-century aqueduct, built to carry water to the nearby Château de Castries with input from Pierre-Paul Riquet, the engineer behind the Canal du Midi. The Pont sur la Cadoule sits close to the walking route that leads to this aqueduct, so the two make a natural pairing: a short walk along the Cadoule takes in both the modest 18th-century bridge and the aqueduct's imposing arches rising above the valley. It's a quiet spot for a photo-friendly stroll, away from the region's busier landmarks.
