              History of the castle 
               
                
               
            In his "reasoned 
              Dictionary of medieval architecture", the French architect 
              Eugene Viollet the Duc describes with a care meticulous person the 
              incredible fortress of Vincennes. We leave the word with this expert. 
               
               
                
              The art of the fortification which had made, at the beginning of 
              XIIIe century, a great step, and which had remained about stationary 
              during the course of this century, made new progress in France during 
              the wars of 1330 to 1400. When Charles V had brought back the order 
              in the kingdom, and taken again a considerable number of places 
              to the English, it made repair or rebuild almost all defenses of 
              the cities or castles reconquered, and in these new defenses it 
              is easy to recognize a method, a regularity which indicate an art 
              advanced and based on fixed rules. The castle of Vincennes in is 
              an example. Built in plain, there was not to benefit there from 
              certain particular provisions of the ground; also its enclosure 
              is it perfectly regular, as well as the keep and its defenses. All 
              the towers are barlongues or square, but high, thick and provided 
              well at their top of projecting watch towers flanking the four faces; 
              the keep is also flanked with the angles of four turrets; the distances 
              between the turns are equal; those are closed and can be defended 
              separately. The castle of Vincennes was started with Philippe de 
              Valois and was completed by Charles V, except the vault, which was 
              finished only under François Ier and Henri II.
