The carrelets of Saint-Palais-sur-Mer are among the most emblematic elements of the Charente coastline. Their history blends traditional fishing, tourist development, and local heritage. 🐟 Origin of the carrelets Originally, the word "carrelet" referred to a square fishing net used since the 17th century. A precise description can be found as early as 1769, in the writings of the scholar Henri-Louis Duhamel du Monceau, who mentioned this type of fishing on the Saintonge coast. 👉 At that time, these were not yet the current huts, but simply a net operated from rudimentary structures. ⚓ Artisanal fishing structures The first local carrelets were simple wooden platforms, built by the fishermen themselves to stand above the water. They were mainly used to catch shrimp, fish, and crabs near the shore, without going out to sea. 👉 It was a family and coastal fishery, less dangerous than sea fishing. 🏖️ 19th – early 20th century: transition to a leisure activity At the turn of the 20th century, with the rise of seaside resorts like Saint-Palais, the carrelets evolved. Holidaymakers and notable figures adopted this practice: construction of fixed jetties, appearance of huts on stilts. The carrelets then became places for relaxation as much as for fishing. 👉 They already contributed to the postcard image of the coast. 🪵 After 1945: democratization and multiplication After the Second World War, the number of carrelets increased sharply. They became a symbol of popular leisure and conviviality. The transition was gradually made from a means of subsistence to a recreational activity. 🌊 Storms and reconstruction The carrelets are fragile in the face of storms: 1999: massive destruction (up to 90% in some areas) 2010 (Xynthia storm): new damage Many have been rebuilt identically, respecting tradition. 🏛️ Today: protected heritage In Charente-Maritime, there are about 400 carrelets. They are: integrated into the public maritime domain allocated by administrative authorization (often renewed every 5 years) Since 2018, they have been recognized as cultural heritage of the department. 👉 In Saint-Palais, they can be observed in particular: at Pont du Diable at the conche du Concié at the Puits de l’Auture

The port of Ribérou is a major heritage site in Saujon, bearing witness to a prosperous maritime past linked to the salt and wine trade. Transformed in the 19th century by ambitious works, it has now been reinvented as a place for living, relaxation, and preserving local history. 🛶 Origins and the Middle Ages The port of Ribérou takes its name from the Latin word ripa ("riverbank") or the Occitan word ribèira ("river"). It is located at the head of the Seudre estuary. It existed as early as the 11th century and became an important river and sea port thanks to its strategic position at the head of the estuary, used particularly for the salt trade—then called "white gold"—a highly sought-after product for preserving food. 🚢 Medieval Period and International Trade With the opening of British markets during the reigns of Eleanor of Aquitaine and Henry II Plantagenet, ships laden with wool, salt, wine, and other goods flocked to Ribérou. In the 16th century, the port exported local wines (such as cognac and pineau) throughout Europe. In 1577, during the Wars of Religion, the port was a strategic site: troops were stationed there, and battles took place. 🏗️ Decline, Reconstruction, and the 19th Century The estuary gradually silted up, making navigation difficult. By 1691, only smaller vessels could dock there. During the French Revolution, the sale of the tidal mill, which helped remove sediment, worsened the silting, leading to the port's decline. A modernization project began in 1822, but it wasn't until 1839 that an ambitious program was launched under the impetus of Jules Dufaure—a native of Saujon and Minister of Public Works—with the construction of sturdy quays, slipways, a lock bridge (marking the boundary between fresh and salt water), and reception facilities. In 1842, the work was completed, and the main quay was named Quai Dufaure in honor of this political support. 📉 Gradual Decline and Modernization The arrival of the railway in 1876 and the persistent problems of silting led to a decline in the port's traditional commercial activity, already facing competition from other transport networks. In the 20th century, the port gradually lost its economic importance but remained active for traditional fishing and became a place for pleasure boating, leisure, and local culture. Urban and tourism development projects (particularly in 2011–2012) modernized the port while preserving its historical charm. 🌊 Today The port of Ribérou is now a small fishing and pleasure port, much appreciated for its walks along the Seudre River, water sports (canoeing, kayaking, paddleboarding, etc.), and seasonal events.

The flushing lock is located at the head of the port, between the north bank's embankment and the south bank's quay. A retention basin, occupying the non-navigable Seudre riverbed as far as Saujon, follows the flushing lock. Within the retention basin, rubble stone embankments extend the lock's return walls for a few meters. The lock itself forms a bridge carrying a road. The lock bridge consists of two piers, forming three arches, each housing two gates. On the upstream side of the lock, the piers have semicircular cutwaters. The three bands are stacked and terminate in clamps. The lock ends with a cornice resting on modillions. The cornice follows the shape of the cutwaters. A metal balustrade, also semicircular in shape, is fixed to the top of the lock. This balustrade is framed by two stone moldings. The sluice gate and its upstream and downstream return walls are constructed of dressed stone. The masonry is of medium and regular quality, except for the coping of the return walls, which features large and regular masonry. The upstream north return wall is lower than the one on the south bank. A small parapet of recently constructed white rubble masonry surmounts it. The sluice gate is equipped with metal gates, the modern racks of which are visible. The first sluice gate was built around 1825 on the site of a former tidal mill. During the works carried out between 1839 and 1842, the sluice gate's embankment was modified to allow the passage of vehicles. Between 1847 and 1853, the lock was enlarged to allow for larger flushes, and the reservoir was excavated. Return walls were also built to connect the flushing lock to the riprap. It was then restored in 1865 and completely rebuilt between 1868 and 1869. The lock is 10.50 m wide, and its gates are each 1.50 m wide. The reservoir is 700 m long and has an average width of 30 m.
