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

📍 Introducing the Gilet Cove The Gilet Cove is a small, natural beach on the oceanfront, located on Boulevard de la Conche de Gilet / Boulevard de la Falaise, in the town of Vaux-sur-Mer, just before Royan. 🌿 It's a sheltered, rocky cove, appreciated for its tranquility and more intimate setting compared to the larger urban beaches nearby. 🏖️ At high tide, the sea can completely cover this small beach, making the space very limited; at low tide, you can enjoy a patch of sand and rocks for relaxing or swimming. 🧭 Features & Tips 📍 Type of place: small, unsupervised beach, nestled among the rocks with sand and cliffs. 🏖️ Tides: access is best at low tide — at high tide the beach can disappear underwater. 🐶 Animals: prohibited from April 1st to September 30th (subject to municipal regulations). 👣 Access: via stairs from the boulevard above, surrounded by villas with sea views. 🚫 Lifeguard services: no lifeguard station or marked services. 📍 Location La Conche de Gilet is often considered the last small beach in Vaux-sur-Mer before reaching Royan/Pontaillac when following the coastline from Saint-Palais-sur-Mer.

Here you can observe local sea salt production. There's a small hiking trail between the sea salt fields and a shop where you can sample and purchase fresh sea salt.
