The Château de Montsoreau is a Flamboyant Gothic castle in the Loire Valley, directly built in the Loire riverbed. It is located in the market town of Montsoreau, in the Maine-et-Loire département of France, close to Saumur, Chinon, Fontevraud-l'Abbaye, and Candes-Saint-Martin. The Château de Montsoreau is situated at the confluence of two rivers, the Loire and the Vienne, and the meeting point of three historical regions: Anjou, Poitou, and Touraine. It is the only château of the Loire Valley built directly in the Loire riverbed.
A Gallo-Roman origin has been verified for the settlement of Montsoreau but not confirmed for the castle, even though a fluted column made of stone from a Gallo-Roman temple or a public building was found in the moat during the restoration works of the end of the 20th century.
