The Loire River valley in central France is home to several impressive medieval castles built between the 15th and early 16th centuries by French royalty and nobility. Chambord, Chenonceau, and Amboise are among the most famous castles along the Loire River, known for their distinctive Renaissance architecture and placement strategically along the river. These grand castles were statements of wealth and power for their owners during the Middle Ages and remain popular tourist destinations today for their beauty and historical significance.
