The Loire Valley is a UNESCO World Heritage Site and one of the most remarkable regions for its rich heritage. The presence of a vast variety of cultural monuments and world-famous castles has earned it international renown. More than a hundred castles line the Loire River and its tributaries: the Cher, the Indre, the Loir, and the Vienne. Nowhere else in Europe, or even in the world, can such a high concentration of castles be found. In the Loire Valley, the history of France is told through its sites and its majestic gardens.
