1205
As early as 1200, John Lackland, who was aware of the strategic importance of Chinon, prepared the fortress for war.
After the capture of Normandy, Philip Augustus left to conquer Touraine. In the autumn of 1204, the armies of the king of France laid siege to the fortress. Hubert du Bourg had been Constable of Chinon since 1203 and supported the siege against Philip Augustus until 1205. He was a great warlord who was able to play an active role in the design of the defence of the Royal Fortress of Chinon. Despite this, Philip Augustus took the castle on 23 June 1205, after a nine-month siege.
The day after his victory, Philip Augustus had to reactivate the defensive capacities of the fortress, which had been weakened by the siege. He had a large round tower built, the Coudray tower.
