Sainte-Geneviève Library (French: Bibliothèque Sainte-Geneviève) is a public and university library located at 10, place du Panthéon, across the square from the Panthéon, in the 5th arrondissement of Paris. It is based on the collection of the Abbey of St Genevieve, which was founded in the 6th century by Clovis I, the King of the Franks. The collection of the library was saved from destruction during the French Revolution. A new reading room for the library, with an innovative iron frame supporting the roof, was built between 1838 and 1851 by architect Henri Labrouste. The library contains around 2 million documents, and currently is the principal inter-university library for the different branches of University of Paris, and is also open to the public.
