The national library is home to a vast collection of historic documents from France and around the world. Its archives include 5,000 Greek manuscripts, offering a unique glimpse into centuries of knowledge and culture.
Visitors have the option to purchase a day pass, which allows access to explore the library's rich collections. For those interested in specific topics, the library also hosts a variety of special exhibitions that showcase selected items from its holdings. Guests can choose to visit these exhibitions without purchasing a full day pass for the general collections.
