Les Invalides was established in 1671 by King Louis XIV. The building was originally designed to be a hospital and home for 6,000 wounded soldiers who had served in the French army. This purpose is reflected in its name, “Hôtel des Invalides,” meaning “Hotel of the Disabled” in French.
Today, Les Invalides continues to provide care, still serving as an infirmary. Over time, its role has expanded to include cultural and historical functions. The impressive complex also contains the Musée de l'Armée, the national military museum, which displays a wide range of artifacts from France’s long military history.
Attached to the main building is the striking l’Eglise du Dôme, recognizable by its brilliant golden dome. This church holds a special place in French history, as it is the final resting place of Napoleon Bonaparte. The tomb draws visitors from around the world who come to see the elaborate monument beneath the dome.
