They are heavily politicized in their presentation of France history (for example one of the spectacle is about the christians persecutions in Rome, where the christians are the good guide, and the romans are the bad guys).

Another famous recent event is that they bought one of Joan of Arc ring, but it was mainly a nationalist move more than something important to preserve (Joan of Arc is from the east / north part of France) (for more infos: https://fr.wikipedia.org/wiki/Anneaux_de_Jeanne_d%27Arc).

Overall, the parc is an entertainment place as much as a political tool, but not a lot of people are aware of it, and most of them are eating their propagande like the true story of France (due to lack of education on history mainly).
