Musée de l'Homme fills part of the Palais de Chaillot with exhibits on human evolution, cultures, and societies. It is a strong stop if you want a museum near Trocadéro that is not just about the Eiffel Tower view.
The displays are broad rather than intimate, moving from prehistory and biology into the ways humans organise, adapt, and explain themselves. The building also puts you close to one of Paris's classic river panoramas.
