This is the famous The Hôtel National des Invalides. It used to be a hospital. But today it's a museum.
This is where Napoleon and other famous Frenchmen are buried.
Plus, it has other super cool information about the history of France. Here's the link to the website: http://www.invalides.org/pages/anglais/historique_a.html. Ask an adult to help you use the website because it's a little complicated but it's worth looking at.
Later I'll blog about my surprise adventure - in the sky! Can you guess what I did? Check back tomorrow to find out more.
Bye for now,
