Top photo - Looking NW toward the modern downtown: The Palais de Chaillot is located in the 16th arrondissement of Paris, between Place du Trocadéro and Place du 11 novembre and the Trocadéro gardens, just a stone's throw from the Paris Aquarium. Built for the 1937 International Exhibition of ‘Arts and Techniques Applied to Modern Life’, it comprises two neo-classical pavilions separated by an esplanade, the Parvis des Droits de l'Homme. The Palais de Chaillot is home to four major cultural institutions: the Cité de l'architecture et du patrimoine, the Musée national de la Marine, the Musée de l'Homme and Chaillot - Théâtre national de la Danse.

LR - Invalides: The clue is on the name...
Louis XIV intended the building to be a home and hospital for disabled soldiers. It also served to hide the disabled veterans from public eye... As fate would have it, during the French Revolution these same veterans let the revolutionaries in so that they could get hold of weapons to take the Bastille.

Napoleon’s Tomb
The tomb is in the Royal Chapel, in an open crypt which lies beneath the Golden dome of Les Invalides: An imperial position! INTERESTING - The Emperor’s remains are divided between 6 caskets, placed one inside the other like Russian nesting dolls and weighing a total of 1200 kg (2600 pds).
