However, Centre is not situated in the geographical centre of France, and the name has been criticized as being too dull and nondescript. Proposed names for the region include Val de Loire after the Loire Valley (the main feature of the region) or "Cœur de Loire" (i.e. "Heart of Loire").Val de Loire is associated with positive images of the Loire Valley, such as the chateaux, the gentle and refined lifestyle, wine, and the mild and temperate climate, all of which attract many tourists to the region. The proposal has not yet been adopted, but the term is sometimes juxtaposed as Centre - Val de Loire. The region includes the rich, fertile valleys of the Loire River and its tributaries: Cher, Indre, Loiret.
