Fondation Cartier pour l'art contemporain

One of the truly great venues for the performing arts anywhere in the world, Paris' new opera house actually managed to inspire some neighborhood protest during its planning and construction. Pretty much everybody is a believer nowadays though. Check out the website for upcoming shows, it might even make sense to plan a trip to Paris around one.

Suspended above the train tracks this garden is surprisingly calm and chilled-out.

It was conceived by Louis XV as a grand neo-classical church honouring St. Geneviève, the patron saint of Paris. After the Revolution, the building was converted into a mausoleum for the great philosophers, military, artists, scientists, and heroes of the French Republic. Occupants of the crypt include Voltaire, Rousseau, Victor Hugo, Zola, the Curies, and Alexandre Dumas (reinterred here in 2002). The view from the dome (206 steps) is marvellous. Check tour departure times at the information desk. A fascinating reconstruction of Foucault's pendulum also hangs within the Panthéon.

For an interesting take on Paris, check out the underground sewers of Paris. See swords found in the sewers over the years and get an appreciation for what it takes to keep Paris running.

Try to visit the cabinet des Médailles.

An 8-storey block of flats, built in 1932–1934.

CLOSED UNTIL LATE 2024 OR 2025 FOR RENOVATION WORKS. Built in 1900 for the universal exposition, the Grand Palais was an engineering feat and a milestone of design, marking the transition between historicism and modern architecture. It remain impressive today due to its unique, exquisite style and sheer volume of its main nave. The Grand Palais, managed by the state-owned institution Rnm who also manage the Musee de Luxembourg, is used both for temporary exhibitions of historic and contemporary art collections (both beaux arts and applied) and unique events, such as catwalk shows during the Paris Fashion Week, Bonhams car auctions and prestigious galas.

20th- and 21st-century art in a building designed by Frank Gehry

17th century church.

Founded in 1671 by Louis XIV as a hospital for 6,000 wounded soldiers—this function explaining the name of the building—the golden-domed Hôtel des Invalides still functions as an infirmary and now also houses the Musée de l'Armée. The church attached, l'Eglise du Dôme, houses the tomb of Napoleon.

Tourists cross this park with the large fountain on the way to the Place du Trocadéro viewpoint to the Eiffel Tower.

A sculpture by Auguste Rodin in memory of the French novelist Honoré Balzac. The artwork is sometimes considered the first truly modern sculpture.

If the queues at the Eiffel Tower are just too much for you and your time is limited, consider a trip up the Montparnasse Tower. This is an office building with an observation and shopping area on the 56th floor, where the elevators stop, and an open viewing area on the roof. Arguably the view is better than from the Eiffel Tower: you are not so high up so things are more visible, and you can see the Eiffel Tower!

One of the best-known and most beautiful churches in Paris, in the guise of a Corinthian order classical temple. Construction started in 1764, although the church was not finally consecrated until 1845. The Madeleine has a lavish interior of marble and gold.

Once the dye works for royalty, it is now a museum.

The magnificent setting of The Phantom of the Opera, the inside is as opulent as the outside. However, since the opening of the Opera Bastille (12th) in 1989, the Palais Garnier has been reserved mostly for dance performances, particularly ballet.

The house of the symbolist painter has now become a museum to his life and work.

An ancient Roman theater, the only surviving above-ground ruins of the Gallo-Roman era in Paris (ancient Lutetia, French Lutèce) apart from the nearby Thermes de Cluny. The theatre could hold approximately 15,000 spectators and measures some 132 m x 100 m. Built sometime in the 2nd century CE, the location of the actor's dressing room, the platform of the stage, and lapidary remains can still be seen. The remains were rediscovered in 1869, when new streets were being built. An excavation was subsequently ordered in 1883. The theatre has been preserved as a quiet archaeological park removed from the bustle of Parisian streets.
