The Latin Quarter shows itself better from a narrow street than from a square. Turn into one of the lanes that climb towards the montagne Sainte-Geneviève, and there at the end of it, framed between two rows of houses, you’ll see the grey dome of the Panthéon. Around that hill you’ll find a museum of the Middle Ages inside a set of Roman baths, a library of naturalists, a mosque, the arena of Lutetia and the historic seat of the university of Paris.
Before you put the quarter in your plans, take one thing off the list: the Sainte-Chapelle is not here. It stands on the Île de la Cité, on the other side of that arm of the Seine, and plenty of guidebooks file it under the fifth arrondissement out of habit. The Panthéon, on the other hand, is here, right at the centre, and on 1 October 2026 it changed both its price and its hours, dropping to the low rate like almost every French national monument.
Which of these museums will still ask you for a ticket when you have a Paris Museum Pass in your pocket?
Let’s go!
Mondays, Tuesdays, and the Monday the Panthéon opens at noon
In the Marais nearly every museum closes on the same day. Not here, and the difference will change your plans: Cluny and the Institut du monde arabe close on Mondays, the Grande Galerie de l’Évolution closes on Tuesdays, and the Panthéon doesn’t close on any day of the week. The only days out are 1 January, 1 May and 25 December.
So on a Monday you do the Panthéon and the Grande Galerie, and give up Cluny and the Institut du monde arabe. On a Tuesday you do Cluny, the Institut and the Panthéon, and leave out the Grande Galerie. From Wednesday to Sunday you get the whole circuit, and the best day of all is the first or third Thursday of the month, when Cluny stays open until 21:00.
Attention: on the first working Monday of each month the Panthéon opens at 12:00 instead of 10:00. In October 2026 that day is Monday the 5th, and it’s exactly the kind of detail that wastes a whole morning if you turn up believing otherwise.
Two more things weigh on a weekend. On Saturdays and Sundays the Institut du monde arabe closes an hour later, at 19:00, and it stays open on public holidays as well, apart from 1 May: over a long weekend it’s the one place in the quarter you can count on without checking anything. And the Jardin des Plantes, the big park of the fifth arrondissement, opens every day of the year and asks for no ticket at all.
1. The Panthéon, and the price range to know before you pay
The ticket changes twice a year, so don’t trust the figure you remember. From 1 October to 31 March the full ticket costs 13 euros and the monument closes at 18:00; from 1 April to 30 September it costs 16 euros, except on Wednesdays, when it stays at 13, and it closes at 18:30. It opens at 10:00 in both seasons, and last admission falls 45 minutes before closing: turn up after that and you stay outside, ticket in hand or not.
What you pay for covers the nave and the crypt, where the tombs of Voltaire and Rousseau face each other although the two men loathed one another in life, and where Marie Curie lies, the first woman admitted here on her own merits. It does not cover the view, because the walkway around the colonnade is closed for works and the monument has published no reopening date: if you’re going up for the rooftops of Paris, put it off.
A Foucault pendulum swings under the dome, and there’s one thing no label tells you: the sphere you watch moving isn’t the one from 1851. The original sits in a display case at the Musée des Arts et Métiers, over in the Marais, where a snapped cable dented it beyond repair.
Slow down over the free admissions, because they come in two kinds and they concern you in different ways. Walking straight in, without stopping at the desk, are accompanied under-16s and disabled visitors together with their companion. Stopping at the desk, to collect a zero-euro ticket, are 16 to 25 year olds who are citizens of the European Union or legal residents in France, French teachers with the pass éducation, and jobseekers holding a certificate less than six months old. The first Sunday of the month is free only in January, February, March, November and December, so on Sunday 4 October 2026 you pay and on Sunday 1 November you don’t. And if the royal basilica outside the city is also on your list, the Panthéon sells a joint ticket with Saint-Denis at 26 euros, valid all year round.
The eight stops between the nave and the crypt, pendulum included, I’ve lined up in Panthéon: 8 stops.
2. Musée de Cluny, the Middle Ages inside Roman baths
Walk down from the Panthéon towards the boulevard Saint-Michel and in five minutes you’re standing in front of a building that is two buildings: a late fifteenth-century Gothic mansion sitting on top of Roman baths of the first century, with the frigidarium still standing and its vault intact. Inside you’ll see the six tapestries of the Dame à la licorne, the heads of the kings of Judah hacked off the front of Notre-Dame in 1793 and found again in a courtyard in 1977, and one of the richest collections of medieval ivories in Europe.
The museum opens Tuesday to Sunday 9:30-18:15 and closes on Mondays, but look at the time on the desks, which stop at 17:30, 45 minutes before the door does. On the first and third Thursday of the month closing slides to 21:00. The full ticket costs 12 euros and is included in the Paris Museum Pass; that rate applies “outside major exhibition periods”, so with a big show up the price goes higher.
Attention: these Cluny figures don’t come from the museum’s own site. The official page answers only a browser with JavaScript and cookies switched on, and no script can read it: I cross-checked two independent sources that agree with each other and with what I had already verified the same way in September. For the 12 euros and for the hours, a confirmation by phone or at the desk is worth the call.
The six works I would stop at, tapestries included, are in Musée de Cluny: 6 works to see.
3. The Sorbonne, the arena and the streets around them
Here you walk more than you go in, and that isn’t a fallback. Place de la Sorbonne puts the seventeenth-century chapel in front of you, with its dome scaled in slate, the statues in their niches and a clock set into the carving. The square below it has two basins with low jets, where students sit in summer, and it’s the portrait of the whole quarter in fifty square metres.
On the far side of the hill, behind a wall on the rue Monge, are the Arènes de Lutèce, the Gallo-Roman amphitheatre of Paris, which today is a public garden with stone tiers and Parisians playing boules in the middle of it. Admission is free, as it is in the churches of the quarter: Saint-Étienne-du-Mont with its rood screen, Saint-Séverin and the small Saint-Julien-le-Pauvre. With a church’s opening hours, though, trust no printed list: they move with the services, and the only page that really tells you is the parish’s own.
There are three streets to walk, and each one leads into the next. The first is the rue Mouffetard, which drops down from behind the Panthéon between market stalls and bistro signs; the second is the rue Saint-Jacques, which follows the line of the Roman cardo; the third is the riverside between the pont de la Tournelle and Saint-Michel, where the green boxes of the bouquinistes stand.
4. Institut du monde arabe, and the best free thing in the quarter
What can you see here without paying for a ticket?
The panoramic terrace, the library and the bookshop, all three free to walk into. The terrace sits at the top of Jean Nouvel’s building, looks out over the Seine and the roofs of the fifth arrondissement, and opens Tuesday to Friday 10:00-18:00, Saturday and Sunday 10:00-19:00. You’ll find the library open Tuesday to Sunday 13:00-19:00, public holidays included. The bookshop opens Tuesday to Friday and on Sunday 10:00-19:00, and on Saturday until 19:30. If you’re after somewhere to stop halfway through the day without spending, this is it.
The museum itself does cost money, 10 euros, and you only pay it if you’re 26 or over: below that line you get in free with a document, with no residence condition and no nationality condition, which is the widest formula in all of Paris. It opens Tuesday to Sunday, closes on Mondays, and the desks shut 45 minutes before the museum does. It’s included in the Paris Museum Pass.
There’s a reason to go now rather than in three years’ time, and it isn’t impatience: the institute is going to rebuild its permanent display from scratch. The project has gone to the PROJECTILES agency, chosen from five finalists out of twenty-four applications, and the new museum is announced for 2028. The occasion is the gift from Claude and France Lemand, nearly two thousand works, which makes the Institut the owner of the most important collection of modern and contemporary art from the Arab world held anywhere in the West. What opens in 2028 will be the first museum in Europe devoted entirely to the arts of the Arab world from antiquity to today. Right now you see it in an hour and a half for ten euros, and if you come back in two years you’ll find a different place. The seven works I start from are in Institut du monde arabe: 7 works to see.
5. Grande Galerie de l’Évolution, and the four tickets of the Jardin des Plantes
Why do more people buy the wrong ticket here than anywhere else in Paris?
Because inside a free garden there are four enclosures with four different rules, and the entrance gate doesn’t explain any of them. The Jardin des Plantes is free to enter and opens every day of the year. Inside it, the Grande Galerie de l’Évolution costs 13 euros full price and 10 reduced, which become 16 and 13 when an exhibition is up. The Grandes Serres cost between 7 and 9 euros and close on Tuesdays, the zoo costs between 10 and 13 euros and opens every day. The Galerie de Paléontologie et d’Anatomie comparée is the one with the skeletons in a row, which is precisely the picture nearly everyone has in mind when they think of this place, and it is closed for works with no published reopening date.
Two warnings that cost real money. The first: the Grande Galerie closes on Tuesdays, and opens every other day 10:00-18:00, with the desks stopping an hour earlier. The second is about the pass: the Grande Galerie is not included in the Paris Museum Pass, because it belongs to the Muséum national d’Histoire naturelle and not to the Réunion des musées nationaux, and it’s the only one of the quarter’s four main sites that you pay for whatever else you hold.
Two discounts make up for that, and hardly anyone knows about them. Admission is free for under-25s, whether they live in the European Union or outside it, and the reduced rate goes to anyone showing a full-price ticket less than three months old from another site of the Jardin des Plantes, from the Musée de l’Homme or from the Zoo de Paris. If you’ve already done the Musée de l’Homme at the Trocadéro, keep the ticket. The seven stops inside that ship of iron and glass I’ve chosen in Grande Galerie de l’Évolution: 7 stops.
6. The Jardin du Luxembourg and the Medici fountain
The last stop takes you just outside the fifth arrondissement, because the Jardin du Luxembourg formally belongs to the sixth. It remains the western edge of the quarter all the same, and you get there from the Panthéon in ten minutes downhill. It’s free, as every public garden in Paris is, and the thing to look for isn’t the Senate palace but a hidden corner on the east side.
The Medici fountain stands at the end of a long basin of green water, between two rows of stone urns, under the plane trees. In the central niche a bronze Polyphemus leans down from the top of a rock, and below him, in white marble, Acis and Galatea hold each other without knowing that the giant is watching them. It’s the moment before the rock is thrown, staged like a scene from a play, and the contrast between the dark bronze above and the pale marble below does all the work. Around them the rusticated columns and the scrolls are furred with moss, and you’ll see that on this fountain the moss adds something instead of taking it away.
Practical information
Details checked on 2 October 2026 on the official sites of the Panthéon, the Institut du monde arabe, the Muséum national d’Histoire naturelle and the Jardin des Plantes, and on two independent sources for the Musée de Cluny, which does not answer automated requests. Prices and opening hours change: check again before you leave.
Tickets. The Panthéon costs 13 euros from 1 October to 31 March and 16 euros from 1 April to 30 September, with Wednesdays at 13 euros even in high season, and the ticket covers the nave and the crypt. The Musée de Cluny asks 12 euros outside major exhibition periods. The Institut du monde arabe asks 10 euros from anyone aged 26 or over. The Grande Galerie de l’Évolution costs 13 euros full price and 10 reduced, rising to 16 and 13 with a temporary exhibition. Opening hours. The Panthéon opens 10:00-18:00 from 1 October to 31 March and 10:00-18:30 from 1 April to 30 September, with last admission 45 minutes earlier. Cluny opens 9:30-18:15, with the desks closing at 17:30, and on the first and third Thursday of the month it stays open until 21:00. The Institut du monde arabe opens 10:00-18:00 Tuesday to Friday and 10:00-19:00 on Saturday, on Sunday and on public holidays, with the exception of 1 May, when it is closed. The Grande Galerie opens 10:00-18:00, with the desks stopping an hour earlier. Closing days. Cluny and the Institut du monde arabe close on Mondays, the Grande Galerie closes on Tuesdays and the Panthéon opens every day except 1 January, 1 May and 25 December. On the first working Monday of each month the Panthéon opens at 12:00. Closed for works. The walkway around the colonnade of the Panthéon cannot be visited and is not covered by the ticket, and the Galerie de Paléontologie et d’Anatomie comparée remains closed: neither of the two has a published reopening date. Free admission. The Jardin des Plantes, the Arènes de Lutèce, the churches of the quarter and the Jardin du Luxembourg ask for no ticket, and at the Institut du monde arabe the panoramic terrace, the library and the bookshop are free. Everyone under 26 gets into the Institut free, with no nationality and no residence condition, and under-25s get into the Grande Galerie free. At the Panthéon, accompanied under-16s and disabled visitors with their companion go straight in, while 16 to 25 year olds who are citizens of the European Union or legal residents in France collect a free ticket at the desk. The first Sunday of the month is free at Cluny, and at the Panthéon only from November to March. Paris Museum Pass. The pass covers the Panthéon, the Musée de Cluny and the Institut du monde arabe, while the Grande Galerie de l’Évolution stays outside it and is paid for separately. Getting there. Cardinal Lemoine on line 10 serves the Panthéon and the Institut du monde arabe, the two ends of the circuit, and it’s the stop to start from. Cluny - La Sorbonne on line 10 and Saint-Michel on line 4 take you to the Musée de Cluny. Censier-Daubenton on line 7, Jussieu on line 10 and Gare d’Austerlitz on lines 5 and 10 and on the RER C serve the Grande Galerie. Maubert-Mutualité on line 10 and Luxembourg on the RER B close the loop towards the Panthéon and the Jardin du Luxembourg. How long it takes. The Panthéon asks an hour and a half with the crypt, Cluny two hours, the Institut du monde arabe an hour and a half and the Grande Galerie two hours. Four sites in one day are too many: pick two and walk between them, and you’ll still have time to sit down.
How to line them up
Start from Cardinal Lemoine on a day that is neither a Monday nor a Tuesday, and better still on the first or third Thursday of the month. In the morning take the Panthéon as soon as it opens, then go down to Cluny before the desks close at 17:30, and keep the long afternoon for the Institut du monde arabe, which closes late at weekends and gives you the terrace without a ticket. The Jardin des Plantes and the Grande Galerie deserve a half day of their own, and never on a Tuesday.
If the quarter is one stage of a short trip, it fits into the route I’ve lined up in What to see in Paris in 3 days. And if the bill for the tickets looks high to you, take out everything that costs nothing here first, because there is plenty of it: the full list is in Paris for free. The quarter next door, on the other side of the Seine, is the Marais.
