Montsoreau (mɔ̃sɔʁo) is a commune of the Loire Valley in the Maine-et-Loire department in western France on the Loire, from the Atlantic coast and from Paris. The village is listed among The Most Beautiful Villages of France (Les Plus Beaux Villages de France) and is part of the Loire Valley UNESCO World Heritage Site.
Montsoreau was identified under the name Restis (rope or fishnet) at the end of classical antiquity as a port on the Loire at the confluence of the Loire and the Vienne. It has taken its name Mount Soreau (Mont Soreau) from a rocky promontory situated in the riverbed of the Loire and surrounded by water on top of which was built a fortress in 990. There have been three major buildings on this promontory, a Gallo-Roman temple or administrative building, a fortified castle, and a Renaissance palace.
Montsoreau was, until the seventeenth century, a center of jurisdiction and the seigneury of Montsoreau stretched from the river Loire to Seuilly-l'Abbaye and Coudray castle in the south. After the French Revolution, the exploitation of a building stone, the tuffeau stone, abruptly increased its population of 600 inhabitants to more than 1000, maintained during the first half of the nineteenth century. This stone, easy to work, was gradually exhausted, and the population decreased to stabilize again around 600 people. Montsoreau then concentrated its activities on agriculture, wine and river trade until the end of the nineteenth century. During the Twentieth century, Montsoreau has seen river trade replaced by terrestrial trade and the rise of a tourism economy.
The name Mount Soreau (Castrum Monte Sorello, Mons Sorello, Mountsorrell, Monte-Sorel, Monsorel, Munsorel, Muntesorel, Montsorel), appears in its Latin form, for the first time, in 1086 in a cartulary. Mons or Monte (mount) refers to the rocky promontory, located in the river bed of the Loire, and on which was built the fortress of Montsoreau. No interpretation has been given of the name Sorello, which is found in several Latinized forms: Sorello, Sorel, Sorelli.
