Bibliothèque Richelieu
If you love books, libraries, & architecture, then the Richelieu Library is a must-see for you. Part of the National Library of France, the Richelieu site occupies the former palace of Cardinal Mazarin and has been the home of the Royal Library since 1721. Specializing in manuscripts and books on the Performing Arts, Prints & Photographs, Coins, Medals, and Music, to read in the library, you must prove that you’re doing research in the field and buy an access pass. But if you just want to admire the grand reading room, you can enter for free and stand at the entrance and take photographs.
