Musée d'Art et d'Histoire du Judaïsme

Built in 1625, the Hotel de Sully is an interesting house with some sculptures in a beautiful courtyard. The house features special exhibitions, so check listings when in Paris.

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.

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!

The northwest corner of the Bois de Boulogne is occupied by the oldest operating amusement park in the world, the Jardin d'Acclimatation, which is mainly known for offering a wide range of amusements which are appropriate even for very small children. They have miniature roller-coasters for children as small as three years, and the usual range of pony rides etc.

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.

Part gallery - part restaurant - part nightclub, La Cite (Les Docks) is a modern building that is instantly recognisable due to being draped on one side with a large neon green shell covering the stairwells and roof the building. Roughly translated in English as The City of Fashion and Design, this is a trendy spot at the weekends and is used for event like Paris Design Week. The restaurant in the building is open all year round.

Housed in an amazing Art Deco building, purpose-built for the 1931 Colonial Exhibition, featuring an elaborate frieze across the front facade that depicts the achievement of French overseas territories. It houses an Aquarium and an Immigration Museum. The aquarium can be seen in about an hour and is popular with families with small children.

Visitable only by reservation and then only one Saturday every month. A richly decorated palace built for Marie de Medici in the early 17th century, which is now the French Senate. For those interested in seeing a Parisian monument normally unavailable to the public, or for those interested in the inner workings of the French Government. The large Luxembourg Garden is open to the public year-round. The garden is home to the Medici fountain, a children's playground, and vintage toy boats for hire that children push around in the Grand Bassin duck pond (a 90-year tradition).

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

Housed in a former Beaux-Arts railway station (completed in 1900 for the Exposition Universelle, later saved from demolition and converted to its present use), the rambling, open-plan museum is home to the works of the great artists of the 19th century (1848-1914) - Impressionists, post-Impressionists, and the rest - that were formerly displayed in the l'Orangerie. This is perhaps the most spectacular collection of European impressionism in the world—breath-taking rooms full of Manet, Renoir, Monet, Van Gogh, and many others. Impressionist represent the biggest draw, but there is much more to explore.

Try to visit the cabinet des Médailles.

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.

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.

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 early Gothic Cathédrale de Notre Dame (Our Lady) has a 12th century design but wasn't completed until the 14th. Still it is a good example of the development of the style, though the west or main portal is a bit unusual in its rigidity. A April 2019 fire caused severe damage, but after extensive renovation the cathedral was reopened to the public in December 2024.

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.
