The Castle of Chambord is the bigest castle of la Vallée de la Loire. It was bild for the simply reason that the king François Ier wished to be close to his lover la Comtess de Thoury. Its characteristic are his doucle helix stairs placed in the heart of the edifice; a Leonardo da Vinci’s work.
I’m fond of history, I often imagine how it could have been at the time. Chambord is terrific, i visited most of the Castles in la Vallée de la Loire my favorite remains Chenonceau. Even though Chambord is not the one I prefer I recommend its visit.
