Marvel at Chateau de Chambord, the largest and most grandiose of the Loire Valley chateaux with its distinctive French Renaissance architecture featuring 440 rooms, 282 fireplaces, and 77 staircases in a design that reflects François I's ambition to create a hunting lodge worthy of a Renaissance king. Climb the famous double-helix staircase, possibly designed by Leonardo da Vinci during his residence at nearby Clos Lucé, which allows people to ascend and descend without ever meeting—a brilliant architectural innovation that amazed contemporary visitors. Explore the spectacular rooftop terrace with its forest of chimneys, towers, dormers, and turrets creating a magical skyline that resembles an enchanted city more than a traditional castle roof. Walk through the furnished royal apartments including François I's chambers and discover the chateau's history as a hunting lodge where French kings pursued deer and wild boar in the surrounding 5,440-hectare forest park, still the largest enclosed park in Europe. The chateau's massive scale, intricate architecture, and unique blend of French and Italian Renaissance styles make it one of the most recognizable symbols of French royal power and artistic achievement, while its isolation in the forest preserves the atmosphere of a royal hunting retreat unchanged since the Renaissance.
