5th arrondissement
You could say that the 5th Arrondissement is the educational district, as it houses many of the city's colleges and universities. Here you can have an educational experience while you visit the local museums. You can find the Museum of Natural History and the Curie Museum (which will allow you to experience the history of radiology). For those who love sculpture as an art form, you can visit the open-air museum Musée de la Sculpture en Plein Air for free.
