The castle was rebuilt - no argument. However it says that the tower / donjon remained from the 13th Century. In what condition, it's hard to say.
"this tower has stayed put in its original style for more than 800 years" What does 'style' mean? Does that include merlons? Seems to me that merlons are an important part of 'style'. 'Style' would certainly have been important in the original construction.
It may be difficult to get absolute proof from a travel brochure, but that does not mean that all possibilities are eliminated. It just indicates that sufficient evidence is not known or is no longer historically available.
The list may require a high level of certainty; that's fine. Other possibilities can hopefully be evaluated in this discussion.
