Origin and history

The Gate of Nevers, also known as the "Porte du Bas", is a fortified gate built into the medieval enclosure of Saint-Valery-sur-Somme. Built in the 16th century in sandstone, flint and brick, it replaces an older building whose foundations partially remain. His name pays tribute to Louis IV of Gonzague-Nevers, Duke of Nevers, who fought against the League and the Spaniards in Picardia at the beginning of the reign of Henry IV. The duke's coat of arms, surmounted by the motto "fides" (in reference to the Battle of Bouvines in 1214), always adorns the vault of entry.

The structure combines brick and stone, with a two-paned slate roof. The traces of the drawbridge and the herse are still visible, as well as a murated poterne giving access to the strike. On the left, the old dungeon now houses exhibitions. Ranked a historic monument in 1907, the gate illustrates Renaissance defensive architecture and the strategic role of Saint-Valery-sur-Somme, then a port city protected by ramparts.

The monument also bears witness to the communal history: the motto "fides" celebrates the participation of the local militia in the Battle of Bouvines (1214), an episode marking the identity of the city. Owned by the commune, the Porte de Nevers is a rare vestige of the urban fortifications of Picardie, combining medieval heritage and Renaissance adaptations. Its state of conservation allows us to study defence techniques and urban planning of the 16th and 17th centuries.
