Cite de l'architecture & du patrimoine is an architecture museum in the Palais de Chaillot. Its strongest section is the Hall of Casts, where full-size reproductions of major French facades, portals, and sculptural details let you study buildings at close range.
The museum is a good fit for visitors who want context for French architecture beyond a single monument, and it pairs easily with the Trocadero and Eiffel Tower area.
