Underground & cool · Architecture & urbanism centre · € · 4e · Le Marais & Île Saint-Louis
Pavillon de l'Arsenal
Paris's free centre for architecture and urbanism, in an 1879 iron-and-glass hall by the Seine. A large permanent scale model of the city covers the ground floor; the temporary shows upstairs argue over how the place should be built next.
Walk the lit floor model first to orient yourself, then take the upstairs show; closed Mondays.

Wall of Philippe Auguste, Rue des Jardins-Saint-Paul
The longest visible fragment of the 1190 city wall built by Philippe II — 60 m long, with two towers still standing, in the playground of a school. Marais was largely spared by Haussmann (who ran out of money), so wall fragments still survive in courtyards.
Enter Rue des Jardins-Saint-Paul from Rue Saint-Antoine. The fragment is on the south side, easily visible through the school playground railings. There's no plaque — this is just a thirty-second look at a 12th-century wall, accidentally preserved.

Berthillon
31 Rue Saint-Louis-en-l'Île. Family-run since 1954. Closed every August (the family takes holidays), and the queue down the street is the giveaway when they're open. The marrons glacés ice cream is the dark-horse pick over the bright fruit sorbets.
Closed Mondays and Tuesdays — and all of August. The shop itself takes only takeaway, but most cafés on the same street serve Berthillon scoops with shorter lines. Try the marrons glacés (chestnut) and the framboise sorbet together; that's the local two-scoop.

Berthillon
31 Rue Saint-Louis-en-l'Île. Family-run since 1954, sourcing its dairy from a single Norman cooperative. The shop closes every August (the family takes holidays) and on Mondays and Tuesdays year-round.
The shop is takeaway only, with a queue down the street when open. Most cafés on Rue Saint-Louis-en-l'Île serve scoops with shorter lines — Le Flore en l'Île and Le Sorbet d'Antan both work. Try the marrons glacés (chestnut) and framboise sorbet together.
- Île de la Cité & Saint-Louisstop 7 of 7 · 450 m
Église Saint-Louis-en-l'Île
Late-17th-century church on the island's spine. Île Saint-Louis was farmland until 1614; the whole island was master-planned and built within 50 years, which is why it's so geometrically tidy.
The church often hosts free Baroque concerts on summer evenings; check posters at the door. Berthillon ice cream is two doors down at no. 31. Walk the length of Rue Saint-Louis-en-l'Île — every shop is independently owned, by edict.
Within a few minutes' walk
- SO/ ParisRooftop-view splurge hotel€€€ · 1 minA bold five-star on the Seine whose top-floor Bonnie wraps a 360° terrace around the city, with Sunday sunset DJ sets. A splurge you remember.
- Le Temps des CerisesTraditional bistro€€ · 5 minA genuinely small bistro on a quiet street near the Bastille edge of the 4th, where the weekday lunch still lands at €13 and the zinc counter predates most of the neighbourhood's boutiques. Plat-du-jour French without apology.
- Musée de la Magie et des AutomatesMagic & automata museum€€ · 5 minIn sixteenth-century vaulted cellars under the Marais, a thousand years of deception laid out as hardware: more than 100 automata, distorting mirrors, trick boxes and Robert-Houdin ephemera. Admission folds in a short live conjuring turn.
- Institut du Monde Arabe rooftop terraceFree viewpoint€ · 9 minTake the lift to the ninth floor of Jean Nouvel's building — its south wall a grid of 240 photosensitive metal apertures that open and close like camera diaphragms — and walk onto a free terrace facing the apse of Notre-Dame across the Seine.
- MIJE MaraisHistoric-mansion hostel€ · 10 minThree seventeenth-century hôtels particuliers — Fourcy, Fauconnier and Maubuisson — run as a single hostel within a few minutes' walk of each other, a few streets back from the Seine. Stone courtyards, beamed dorms, a non-profit that has held these buildings since the 1960s.
- Pasta LineaFresh pasta counter€ · 10 minA ten-seat Marais counter where Sylvie Pronzato and Alexis Pottecher make everything on site from organic flour and Italian produce. The rigatoni, lasagna and vegetable-laced penne are cooked to order, and the tiramisu is worth the wait.
The district · 4e
Le Marais & Île Saint-Louis — Medieval Paris, intactPlace des Vosges, the Pletzl's falafel, the Hôtel de Ville, and the impossibly tidy Île Saint-Louis. Beautiful and busy; the streets weren't built for the weekend numbers they now carry.
Best for: Walkers and romantics who want the storybook streets and will trade quiet for it.
