Musée des Arts et Métiers

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.

Those who are unfamiliar with conceptual art sometimes don't know quite what to expect, or how to approach it. Such travellers should rest assured that the curators at the Pompidou Centre have assembled a marvellous introduction consisting of mostly approachable works which delight, amuse, and entertain. The art is far from the only reason for a visit, as the building also contains a vast public library and a fine restaurant (run by the Costes brothers) on the roof. In fact the place is literally surrounded by some of the nicest pavement cafés in the city, in its superb location between the car-free above ground part of Forum Les Halles and the Marais art district.

The building has a freely accessible rooftop which allows for a beautiful bird's-eye view of the northern half of Paris.

One of the three islands on the river Seine

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

The house in which the famous French novelist Victor Hugo once lived.

This charming scientific museum preserves the offices and laboratories of Pierre and Marie Curie, pioneers in the discovery of radioactivity. Their instruments, equipment, and furniture is arranged as it was during their critically important research. Guided tours in English available.

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

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.

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

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.

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.

Paris's international exhibition centre (the 4th largest in Europe) has millions of visitors annually.

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.

The first concrete church

Most of the works by Picasso and others which were in the master's possession at the time of his death are now on display here.

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

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.
