Musée du quai Branly

One of the most eye-popping sights of Paris, the catacombs represent a network of labyrinthine tunnels, first excavated in the Roman period, that now house the remains of over 6 million burials removed here from the various overcrowded cemeteries and charnel houses all over Paris in the late 18th and early 19th centuries. Well worth a visit: the atmosphere is suitably morbid and gloomy (without being too scary), the dark tunnels containing neatly stacked piles of skulls and long bones. There is a limit to the number of visitors allowed within the Catacombs at one time (200 persons). So, if you arrive just after opening, you must wait until someone exits, approximately 45–60 minutes, before anyone is admitted. Steep stairwell on the exit of the catacombs. Can be challenging for the elderly or the unfit. Tickets can be purchased online at a small premium (€29, includes audioguide), allows you pick a date&time and to skip the long line

Famous people who stayed here include Marie de Rohan, intriguer during the Fronde; Jeanne Baptiste d'Albert de Luynes, future mistress of a duke of Savoy; Marie Angélique de Fontanges, mistress of Louis XIV, died here giving birth to his child who also died. Today its main cloister (illustration) forms part of the modern Hôpital Cochin.

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.

There are a number of famous occupants, but the real reason to visit this cemetery is to see the ornate tombstones, sculptures, and other sometimes macabre, sometimes touching memorials Parisians have left here for their dead.

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.

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.

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.

Contained within two historic houses (hotels), the museum explores the history of Paris through objects in over 140 separate rooms.

The largest French museum of Jewish art and history

The two pavilions were built in 1784 to 1787 by the French architect Claude-Nicolas Ledoux, who erected many similar toll houses at the entrances to the city.

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.

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

The Musée Grévin is a waxwork museum with some 500 characters arranged in scenes from the history of France and modern life.

The national library preserves collections of historic documents of both French and international origin. It holds 5,000 Greek manuscripts. You can get a day pass to visit or choose to visit only the expositions the library hosts.

The official residence of the President of France since 1848. Dating to the early 18th century, it contains the office of the President and the meeting place of the Council of Ministers. It is located near the Champs-Élysées in the 8th arrondissement of Paris, the name Élysée deriving from Elysian Fields, the place of the blessed dead in Greek mythology. Not open to the public, except occasionally during the annual National Heritage Days (usually a weekend in mid-September). Important foreign visitors are hosted at the nearby Hôtel de Marigny, a palatial residence.

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.

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.

Guimard's own home, built in 1909-12. It is less decorated than Castel Béranger, but still beautifully shaped. 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.

An industrial design museum in Paris that houses the collection of the Conservatoire National des Arts et Métiers (National Conservatory of Arts and Industry), which was founded in 1794 as a repository for the preservation of scientific instruments and inventions.
