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

Here you'll find a romantic little lighthouse, and behind it lies a garden with a bench overlooking the sea, a lovely place to stop for a break. Afterwards, you can continue along the cliff to the right until you reach Euro Velo 1 again.

The Terre-Nègre lighthouse is a landmark forming a cylindrical tower a little over 26 meters high. Located on the tip of Terre-Nègre, in the commune of Saint-Palais-sur-Mer, in Charente-Maritime, it is intended to mark the southern pass of the Gironde estuary and to signal the presence of a dangerous sandbank, the "Anglais bar". This building forms a tower-column 3.16 meters in diameter and 26.60 meters high. A spiral staircase with a central core of 143 steps leads to a summit platform equipped with a directional light. The tower is painted in two different colors to make it more visible: the upper part is red, the lower part is white. The base of the lighthouse is hidden by a building that once served as the keeper's accommodation. The installation of a beacon at this location was considered as early as 1763. De Kearney took over the beaconing plan four years later. Construction work on the tower began in 1770 and was completed in 1773, probably under the supervision of the Bordeaux engineer Claude Tardy. In 1807, the tower was raised. However, this work was considered insufficient by some of the estuary's navigators. In 1834, sailors from the nearby port of Royan sent a request to the Ministry of the Navy to study the possibility of equipping the tower with a light. However, this request was postponed the following year due to lack of sufficient funds. A new request from sailors prompted the lighthouse commission to experiment with a first light in 1836. Finally, on October 15, 1838, a fixed white 4th order light was permanently installed. The latter was replaced in 1856 by a fixed white light of the 4th order of a small dioptric model with a reinforced sector of the 5th order catoptric. It was equipped with new lights in 1899 and 1904. In 1939, it was electrified. During the German occupation, the lighthouse served as an observatory for the soldiers of the Wehrmacht. Damaged during the fighting of 1945 (presence of breaches at the top of the tower), it was restored in the immediate post-war period. In March 1947, the lighthouse was operational again. A light with 3 occultations — changing every 12 seconds — was installed. Its colors are white, red and green. Its current range is 18 miles. Listed as a Historic Monument since 2011, the lighthouse is not open to visitors. However, it can be admired from the outside and a pretty passage provides direct access to the coastal path.

The 12th century church (the oldest), was raised in the 18th century when the bell tower was transformed into a beacon for navigation. It is known as "Le Vieux Clocher". Saint-Pallais is a saint of the Catholic Church and the Orthodox Church. He was in the 6th century, the ninth bishop of Saintes. The history of the Romanesque church and the Old Bell Tower is perfectly summed up on the small information panel placed a few meters from the entrance: "The Romanesque church built under the name of Saint-Palais dates from the second half of the 12th century. At present, all that remains of this remarkable building are the choir, the apse, part of the bell tower and a section of the drip wall of the nave (in a construction, the drip wall is the wall carrying a gutter or a channel ending the roof slope and receiving the water as opposed to the gable wall). "The Old Bell Tower" dominates the tombs of the old cemetery, one of the exits of which opens onto the square on the south side of the new church. This 12th century church is distinguished by its architectural sobriety, a refined style and forms of a very Cistercian elegance. Unfortunately, time and wars have largely amputated the building. The octagonal bell tower is in its lower part authentically Romanesque: a semicircular bay adorned each of the faces, but only two of them have been preserved to the south and east. In order for the bell tower to serve as a landmark, a first raising of more than 2 meters was carried out in the first half of the 17th century. A second, a few years later, gave it its current height. Around 1770, a timber spire was added. The apse, vaulted in a cul-de-four is decorated with five basket-handle arcades resting on engaged columns. 3 bays with deep embrasure and framed by two small columns with bare capitals, provide lighting. A chamfered cord goes around the choir and the apse and delimits the vaults of the load-bearing walls. The climb to the top of the bell tower is recommended to enjoy a superb panorama of the Gironde estuary, the ocean, the Cordouan lighthouse, the residential areas of Saint-Palais, the national forest and the surrounding countryside.
