The Château de Chambord (French pronunciation: [ʃɑto d(ə) ʃɑ̃bɔʁ]) in Chambord, Centre-Val de Loire, France, is one of the most recognisable châteaux in the world because of its very distinctive French Renaissance architecture, which blends traditional French medieval forms with classical Renaissance structures. The building was commissioned by king Francis I of France and built between 1519 and 1547.
