A Rhesus macaque stands in its cage at the French CNRS' (National Centre for Scientific Research) primatology centre where various monkey species are raised for the entire French scientific community in Rousset, south-eastern France, on November 6, 2025. At the foot of Sainte-Victoire, between vineyards and olive groves, the cries of monkeys can be heard. A discreet primate centre has been housing and raising hundreds of primates for decades, destined for scientific laboratory experiments. This primate station has been singled out by animal rights activists since it announced plans to triple the number of primates housed there by 2029, reaching 1,800 specimens.
