The history of the commune dates back to before the era of the
Roman invasion, when it was a small settlement inhabited by
Gauls. The Roman invasion encouraged the small hamlet to grow into a small village, and after the Romans left France the village soon came under the power of the
Franks. In 611, the monk Gualaric (Walric), also known as
Valery, arrived in the area. He installed himself as a hermit on the headland of the site of Leuconaus, now the Cap Hornu. His virtue and miracles quickly attracted disciples. These disciples formed a primitive abbey. The saint was then buried there in 622 and the "Chapelle des marins" was erected in 628 by Saint Blimont over his burial place.
Clotaire II (King of Neustrie) provided the foundations of the new abbey in 627. The relics of the saint attracted many pilgrims to the abbey, which had become known as Saint-Valery. During the 8th and 9th century, the abbey and village were plundered and devastated on several occasions by the
Vikings. The village grew during the 10th and 11th centuries and was historically significant as the site where
William the Conqueror assembled his fleet before sailing to
invade England in 1066. During the
Hundred Years' War, the village passed between French, English and Burgundian control, during which the English demolished the abbey and cloister in order to strengthen the nearby St Valery castle. In 1431,
Joan of Arc was held prisoner in the local prison, whence she was then conveyed to
Rouen and burnt at the stake. The cell in which she was held can still be found near part of the old village walls. The commune found peace and prosperity during the 15th, 16th and 17th centuries. The abbey was rebuilt and still stands today. The activity of the port flourished, thanks to the export of the wines and the growth of the
herring industry. It was near enough to
Paris to be one of the earlier suppliers of the
chasse marée merchants. The commune mirrors the history of France, becoming a site of religious conflict between
Protestants and
Catholics and later as a source of conflict during the
French Revolution. The commune was popular during the 19th century with artists and writers and
Victor Hugo,
Jules Verne,
Alfred Sisley and
Edgar Degas all had villas here at one time or another. ==Population==
