Port-Royal Abbey

The C.I.U.P. is a student quarter established in 1925, providing homes for about 10,000 students, scientists, and artists from 120 countries. It has 40 houses attributed to individual nations. The individual houses organise top quality cultural and political events. Among the most remarkable buildings are the Fondation Deutsch de la Meurthe, the Heinrich Heine House (Maison Heinrich Heine - Fondation de l'Allemagne), the Swedish Student House (Maison des Etudiants Suédois), and the Swiss Pavilion (Pavillon Suisse) which was built in 1933 on plans of Le Corbusier.

This charming museum is owned by the French Académie des Beaux-Arts. Its main collection areas, the result of several large donations, include: First Empire art and furnishings; illuminated manuscripts; and Impressionist art, including the largest Monet collection in the world and works by Renoir, Manet, Morisot, Caillebotte and Gauguin.

Castel Béranger is an apartment building that was the first entirely art nouveau building in Paris, insulted at the time as "Castel Derangé". Its richly decorated facade won a city competition in 1898. It contains 36 apartments, all of which are still privately owned and not open to the public.

The oldest church in Paris, founded in the year 542 by King Childebert. The church as it exists today dates mainly from the 11th century, the period in which it became the center of a powerful Benedictine abbey. The Revolution witnessed the suppression of the abbey in 1794, when most of the monastic buildings were put to the torch. Earlier, 318 priests had been hacked to death nearby by a mob on 3 September 1792. The church underwent significant restoration in the 19th century, ensuring the preservation of the building, which by that date represented a fascinating mix of styles: 6th century marble columns placed alongside Gothic vaults and supported by Romanesque arches. Famous burials within the church include René Descartes (philosopher), Nicolas Boileau (poet) and King John Casimir of Poland, who had become (in 1669, before his death) abbot of the church's monastery.

Try to visit the cabinet des Médailles.

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.

Its exhibits come from such diverse origins as ancient Egypt, classical Greece and the Roman Empire, medieval Europe, and Napoleonic France, but controversially including many items that were looted from their places of origin. Its most famous exhibit, of course, is Leonardo da Vinci's painting of the Mona Lisa (French: La Joconde, Italian: La Gioconda), generally to be found surrounded by hordes of camera-flashing tourists. The Louvre poses many of the same challenges to the visitor as Paris itself; overwhelming in size, crowded in high seasons, and much information available only in French. If you want to see everything in the Louvre, plan at least two full days. However, it is better to pick and choose, as the collection was assembled with an eye to completeness rather than quality. As of July 2019, due to intense crowding and reports of ticket fraud, entry now almost always requires a pre-booked timed ticket, even for holders of the Paris Museum Pass.

Recently reconstructed, the Paris branch of the National Maritime Museum, one of the three museums in the Palais du Chaillot, cannot accommodate any full-size ships, but has a wide range of smaller artifacts, artworks and models, covering both the Navy and commercial shipping.

A former fortress and royal residence at the edge of the city, alongside the Bois de Vincennes. Most of the building is open to public.

A Gothic church tower in a square 150m to the west of the Hôtel de Ville was restored by Ballu, is all that remains of Eglise Saint-Jacques-de-la-Boucherie, which was the meeting place in Paris for pilgrims heading to Santiago de Compestela. As such it is included on the UNESCO World Heritage List as part of the Routes of Santiago de Compostela in France.

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!

This museum is in the historic Invalides complex and presents the history of the French Army. It is co-located with Napoleon Bonaparte's tomb (entry to which is included in the ticket price). Most of the exhibitions are very old fashioned, and the coverage of the First World War is surprisingly limited. A highlight is the Musée des Plans-Reliefs, which displays painstakingly accurate models of French fortresses and includes its own shop.

Numerous artists paint portraits of tourists and also sell their paintings.

This wedding cake-white church rises visibly above the north part of Paris. The striking building, with its towers and white onion dome (83 m high), was built between 1875-1914 on the birthplace of La Commune, officially as an act of penitence for the sins committed during the civil war in which thousands of Communards were executed, as well as for the previous bloodshed of the 1870 Franco-Prussian war. A number of prominent businessmen put up the money, and a dizzying combination of architects worked to put together the mock Romano-Byzantine extravaganza. Consecration followed in 1919. The view over Paris from the dome and from the square before it (200 m above sea level) is unsurpassed, apart from that enjoyed at the Eiffel Tower (50 km on a clear day). For the athletic traveller there are stairs from several directions to the top of the hill; otherwise there is also a funicular which runs every few minutes during the daytime from Place St. Pierre. Follow the signs that say "Funiculaire De Montmartre". Beware that the guards don't like it if they catch you taking pictures inside and will even yell "No photo!" and chase you down if they see you with a camera. Be warned: along the lower steps leading up to church, groups of mostly young African men gather and reach toward you with a small string, offering to loop it round your finger. In case it happens, pull back your hand, brush them off and move on. They might claim that "This is for the church." In case your feel that things go sideways, raise your voice to get people's attention and ask them call the police.

The Paris Botanical Garden, founded as the royal medicinal garden in 1626 by King Louis XIII's doctor, contains over 10,000 species. The grounds also include a small zoo known as La Ménagerie, and the Muséum National d'Histoire Naturelle, which includes the Grande Galerie de l'Evolution (where you can see thousands of naturalized animals from all over the world) and the 'Galerie de paléontologie et d'anatomie comparée' (same thing, but with skeletons).

Soaring stained glass windows beaming ample light onto the rich primary colours of the tile mosaics on the floor, this photogenic church was built by the French kings to house the relics of the Crown of Thorns. Make sure you go on a sunny day, as the highlight of this small chapel in Rayonnante Gothic style are the large stained-glass windows which soar up to near the vaulted ceiling. Also of interest is the extremely ornate lower level. If it happens to be rainy or cloudy, give Sainte-Chapelle a miss, as the play of coloured lights on the floor is well worth the wait for a sunnier day. As the chapelle is inside the Courts of Justice, there will thus be a security check.

The sleaze of boulevard de Clichy between place Pigalle and place Blanche can provide a moment of distraction. Be warned if you are male it is better to do this in the company of a female fellow traveller, as the clubs often send the girls outside to attempt to physically drag passing men off of the street. These strip clubs are big ripoffs. They tempt you with a free drink for €10 entry; once in the girl who starts dancing orders a couple of drinks (Red Bull) and then before you realise you are presented with a bill ranging from €500-700. They have these big bouncers who threaten/manhandle you till you arrive at some settlement with them. The whole of Pigalle is a rip off, best avoided. The police know about these places but nothing is done.
