The Tour de Moricq has always been surrounded by legends. It was once said that an underground passage would connect it to the Angles church. Also, strange signs engraved on the north facade are said to be a plan to find a treasure buried in its depths. According to tradition, it would be a golden chest which would only be accessible at the time of the Sanctus of Midnight Mass, at Christmas. According to another legend, the tower was built by fairies in a single night.

Classified as a Historic Monument in 1915. Originally a sentinel at the edge of the mainland, then a prison and finally a granary, the Moricq Tower has suffered greatly, throughout its history, from the repeated insults of time and men. For more information on visits: 02 51 97 56 39

The origins of the city of Luçon are linked to port activity dating back to the early Middle Ages, when the city was located on the edge of the Gulf of Pictons before the drying up of the Marais Poitevin. Luzon was then a fortified town, whose ramparts, protected by water moats, can be seen in the layout of the streets surrounding the town centre. Throughout the 19th century, the commercial activity of the port of Luçon with northern Europe in particular, which for a time even made it the third largest grain port in France, contributed to the enrichment of the city. This activity stopped in the 20th century with the silting of the canal which connected the city to the coast. But Luzon is best known for its religious status. From the 7th century, the foundation of a monastery which was destroyed by the Viking invasions made it the spiritual center of Bas-Poitou and the town became the seat of the bishopric in the 14th century. In 1608, a certain Armand Jean du Plessis was appointed Bishop of Luçon. Noting the sad state of the city ravaged during the Wars of Religion, he described the region as "the ugliest bishopric in France, the dirtiest and most disagreeable" (especially in order to justify his request for subsidies from the ecclesiastical authorities). endeavored from then on to reorganize the diocese which he left in 1623 to put himself at the service of the king, after a long ascent to the throne.This bishop of Luçon, with remarkable intellectual qualities, ended up becoming the principal Minister of Louis XIII, and remains known under the name of “Cardinal of Richelieu.” The history of the city remains intrinsically linked to the figure of Richelieu who officiated in this cathedral. Begun in 1091, the cathedral was initially in the Romanesque style. The portal of the north transept remains from this period. But for the most part, the building (the nave, the choir, the cloister) that we see now was rebuilt several times in the Gothic style. During the wars of religion, the church was repeatedly ransacked. The high openwork neo-Gothic spire is a splendid romantic fantasy according to 19th century taste. It peaks at 85 m and gives the cathedral the silhouette we know today. The city center of Luçon also offers other historical and religious monuments.

The site of Mareuil sur Lay corresponds to that of an old city marked by the proximity of the sea. Former port, it welcomed the barges (traditional boats dedicated to the transport of goods) which went up the Lay by transporting in particular salt. Once at the port, the salt was unloaded and transported overland. Under Napoleon 1st, a national road was laid out, leading to the construction of a new stone bridge and Mareuil became an obligatory passage between La Roche sur Yon and La Rochelle. The bridge you cross here dates from this period and offers a beautiful view of the old town of Mareuil. The town is also at the heart of the Mareuil vineyard, which is the largest and one of the most famous in Vendée. Located on the slopes of the Lay and Yon rivers, it extends over an area of 300 hectares divided between 10 municipalities. Annual production is approximately 17,000 hl.

The gates are dikes, functioning as locks, in order to control the amount of water that is in the marsh, so as not to suffer from fluctuations associated with high and low tides.
