Formerly known as the castle's donjon or "Grosse Tour", this tower is part of Philip's 1204 phase. It is said to have housed one of the sessions of Joan of Arc's trial, one in which she was shown the instruments of torture, to which she replied "Truly, if you have to pull my members and my soul from my body, I shall say nothing else; and if I say something to you, I would always say to you afterwards that you made me say it by force."[citation needed]. She was not imprisoned here but in the now-lost Tour de la Pucelle, whose foundations may be seen at 102 rue Jeanne d'Arc. The pointed roof was added in restoration works beginning in the 1870s. During the Second World War the tower was camouflaged and turned into a bunker by the occupying German forces. It is now open to the public.
