What is it, exactly?
Richelieu is the original home of the Bibliothèque nationale de France: the 17th-century palace of Cardinal Mazarin, which took in the royal library in 1721. Under Napoleon III, Henri Labrouste — the architect of the Bibliothèque Sainte-Geneviève — was brought in from 1854, and his successor Jean-Louis Pascal built the Salle Ovale, an amphitheatre-shaped hall lit through a glass roof and ringed with galleries of books. It served as a periodicals reading room until 2016, then closed for the site-wide restoration, funded in part by more than 2,700 donors, and reopened to the general public in September 2022 after twelve years of works. The crucial point is what it is not: this is not a research library. No pass, no proof of study, no registration, no age limit. Some 20,000 books sit on open shelves, including 9,000 comics, with 160 seats.
Is it worth visiting? — and why not queue and pay at a big-name monument?
Fifteen minutes will do if you only want to look, and the looking alone justifies the trip: the scale of the dome from floor level is genuinely startling. But the reason it beats a paid ticket elsewhere is that you are allowed to stay. Sit down, pull an art-history book or a comic off the shelf, and you get two hours inside a monument rather than a shuffle through one, at no cost. In a July heatwave, the air conditioning is reason enough on its own. One thing to respect: people are working in here. Photograph the room quietly and do not set up a tripod or run a shoot.
How do you get there?
The visitor entrance is at 5 rue Vivienne, 75002, right next to the Galerie Vivienne. Bourse on line 3 is closest at around four minutes; Palais Royal–Musée du Louvre (lines 1 and 7) and Pyramides (lines 7 and 14) are each about eight minutes. Buses 20, 29, 39, 48, 74 and 85 all pass nearby. Step-free access is through the readers’ entrance at 58 rue de Richelieu rather than the Rue Vivienne door.
When to go, and what it costs
Free, no booking. Open Tuesday 10:00–20:00 and Wednesday to Sunday 10:00–18:00; closed Mondays and on French public holidays. Tuesday evening is the quiet slot most people miss entirely. One date to plan around: the BnF shuts all its Paris sites for an annual break, which in 2026 runs Monday 31 August to Sunday 6 September, reopening on the afternoon of Monday 7 September. The separate BnF museum next door — the Mazarin Gallery, the Berthouville Treasure, the Louis XV Salon — is ticketed at roughly €10 and is free for under-26s, so if you qualify, do both.
Insider tip
Do not stop at the Oval Room. The Richelieu site’s garden, terrace, bookshop and café are all free to wander, and you can see into the Salle Labrouste — the other, even more celebrated reading room, with its slender iron columns and nine domes — from the doorway, even though it is a research space you cannot sit in. Then walk out of the Vivienne exit and go straight into the Galerie Vivienne next door, a glass-roofed 1820s shopping passage with a mosaic floor, thirty seconds away and equally free.
