The Loire Valley, spanning 280 kilometres (170 mi), is a valley located in the middle stretch of the Loire river in central France, in both the administrative regions Pays de la Loire and Centre-Val de Loire. The area of the Loire Valley comprises about 800 square kilometres (310 sq mi). It is referred to as the Cradle of the French and the Garden of France due to the abundance of vineyards, fruit orchards, and artichoke, and asparagus fields, which line the banks of the river. Notable for its historic towns, architecture, and wines, the valley has been inhabited since the Middle Palaeolithic period. The oldest known Neanderthal engravings have been found a cave in La Roche-Cotard which have been dated to more than 57,000 years ago. In 2000, UNESCO added the central part of the Loire River valley to its list of World Heritage Sites.

A valley is an elongated low area often running between hills or mountains, which typically contains a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas.
