A French aristocrat descended from Louis XIV is seeking a court order to stop a Japanese artist exhibiting his work at the Palace of Versailles.
Work by Takashi Murakami, who blends Japanese classical art with manga-style modernity, is on show until December.
But Prince Sixte-Henri de Bourbon-Parme believes Murakami’s brightly coloured work dishonours the memory of his ancestors.
The prince and fellow protesters say Murakami “denatures” French culture.
“By exhibiting at Versailles, artists benefit from an added value,” he told the AFP news agency.
