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.
