Traces of the first jetty at the port of Saint-Denis date back to the 12th century, used for transporting Chassiron wine to La Rochelle. Official documents appear in the 17th century, including taxes intended to finance the port's renovation. In the 17th and 18th centuries, numerous works on jetty, dikes, and repairs to combat silting were carried out regularly. Constant silting was the main problem—despite successive works, the port continued to silt up, which hampered its functionality. At the beginning of the 19th century, the idea of a protected port was abandoned and the breakwater was destroyed. Between the 1920s and 1930s, the port was gradually abandoned due to silting, lack of traffic, and also changes in transportation modes (railways, etc.). With the rise of tourism in the mid-late 20th century, the rehabilitation project was put back on the agenda. The new marina was inaugurated on July 23, 1989. It offers several hundred moorings (approximately 700-750 depending on the source) and replaces the old port, which was unusable due to the sand. In 2006, a commercial area and service infrastructure (restaurants, shops, bicycle rentals, etc.) were added around the port to make it more attractive to boaters and visitors.

As you head towards the port, AIDA signs line Port Avenue. In keeping with the association's objectives, AIDA wanted to create a link between the port and the village center and highlight the town's "remarkable points." To date, the thirty or so signs installed allow for a circular stroll through the village. If you would like to view all the signs, click on the link https://aida17650.fr/panneaux-patrimoine/

Enjoy cycling in this remarkable dune forest, covering almost 700 hectares. It's the result of a large-scale reforestation campaign in the 19th century, aimed at halting the dune advance, which was gradually encroaching on villages.
