Témoignage de John Evelyn (1644).
St. Stephen’s church is the cathedral, well-built à la Gothique, full of sepulchres without-side, with the representation of the final Judgment over one of the ports. Here they show the chapel of Claude de la Chastre, a famous soldier, who had served six kings of France in their wars. St. Chapelle is built much like that at Paris, full of relics, and containing the bones of one Briat, a giant of fifteen cubits high. I was erected by John Duke of Berry, and there is showed the coronet of the dukedom. The great tower is a Pharos for defence of the town, very strong, in thickness eighteen feet, fortified with graffs and works ; there is a garrison in it, and a strange engine for throwing great stones, and the iron cage where Louis, Duke of Orleans, was kept by Charles VIII.
