In English one often speaks of the chateau de Montsoreau or Montsoreau. The chateau de Montsoreau was the first of the chateaux of the Loire Valley to be built in the Renaissance architectural style. When the chateau was built, Montsoreau was already a historical village, home of a royal fortified castle. From 1450, when King Charles VII and King Louis XII moved to Chinon and Tours, the Loire Valley became the centre of power of the ancien régime.
