Périgord counts the greatest number of castles in France, they would be more than 1000. Their construction started at the XI century, in “strategic” places (rocky outcrops dominating the valleys) where it was possible to control the passage. Until the end of the Middle Ages, Périgord was cut into two parts, politically (during the one hundred year old war, the Dordogne river separated the kingdom of France from the kingdom of England) and religiously (during the wars of religion between Catholics and Protestants). This explains the impressive number of strong castles, villages and churches strengthened. Along the history and due to successive destructions and rehandlings, their aspect evolved much, passing from the austerity of the Middle Ages with a purely defensive role, with comfort and the light brought to the Rebirth.
