Musée Picasso

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).

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.

A monument to the French art de vivre, housed in a 19th-century wing of the Louvre that has been restored to beaux-arts splendour, its galleries and period rooms showcase eight centuries of Gallic taste in interior decoration.

This street is named in honor for Nicolas Appert, a French businessman who invented airtight food preservation. On January 7th, 2015, it was the site of the Charlie Hebdo terrorist attack, which resulted in the deaths of 12 people. A plaque in front of a former office building memorializes the victims of the satirical magazine's staff.

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

A symbol of Paris and one of the most famous landmarks in the world. Built by Gustave Eiffel in 1887-1889, the tower was almost torn down in 1909 and only saved due to its use as a telegraphy antenna. The queues can be very long. The tower allows online reservations at its website. You can select a date and time frame. If you miss the time on your ticket, you have lost your money. The north, west, and east pillars have elevators that go to the first and second floors; the south pillar has stairs that can be climbed to the second floor. To reach the top floor, an additional elevator ride is required, and the wait for this can be very long as well. Disabled visitors are not allowed beyond the second floor due to safety concerns. Taking the Métro as far as Ecole Militiare and then strolling up the Champ de Mars is a lovely way to arrive at the tower. Another phenomenal approach is to exit the Metro at Trocadero and see the Eiffel Tower from the other side of the Ecole Militaire.

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.

Enter Bastille station through any entrance or on any train and then make your way to the Bobigny/Pablo Picasso-bound platform. All that's left of the fortress whose front steps used to lead up from place de la Bastille are some foundation stones which you can see while waiting for a north bound train on this metro platform. There are maps and explanations showing where the fortress used to be relative the place and surroundings (basically the location of the old front steps are now occupied by Café des Phares).

Opened in 2006, this is the newest and the most modern of Paris' great museums, housing an outstanding collection of tribal art, with a particular emphasis on France's former (and present) territories in Oceania and Africa. The museum is large and you can easily spend half a day browsing, especially if you pause to explore the multimedia presentations.

A controversial church serving as de facto headquarters of the arch-traditionalist Society of Saint Pius X, who occupied the church in 1977 and have ignored subsequent eviction orders.

The largest French museum of Jewish art and history

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.

This iconic triumphal arch forms the focus of the main east-west road axis of Paris, running between the Louvre and the Grande Arche de la Défense in the west. The monument was commissioned by Napoleon in 1806 as a tribute to his victories as Emperor of France - it was finally completed in 1836, long after his death. 50 m (150 ft) high and 45 m wide, the Arc de Triomphe is decorated with battle scenes and martial sculptures that includes La Marseillaise by Rude. The Tomb of the Unknown Soldier was placed beneath the arch in 1920, where an eternal flame burns in tribute to the French dead of both World Wars. The arch is surrounded by a large roundabout, aptly known as l'Etoile - 'the star' - with 12 thoroughfares leading off from it. Visitors can purchase a ticket to climb to the top of the arch, from where magnificent views spread out over western Paris. Admission to a small museum devoted to the history and meaning of the monument is included. The central island and the arch are accessed by an underground passage. Do not attempt to negotiate by foot the busy multi-lane road that rings the Arc de Triomphe, which many Parisian drivers seem to consider their own personal speedway.

There are many beautiful footpaths, a Buddhist Temple, and a lake with rowboats available for rental (about €10 as of 2009). The lake has many different kinds of birds, and islands accessible by footbridge.

Beautiful round "square" with an equestrian statue of King Louis XIV and matching 17th century buildings.

St. Geneviève was responsible for saving Paris from the Huns in 451 and her shrine in the church has been a popular place of pilgrimage ever since. The church as it stands dates from between 1492 and 1626 and is a mix of Gothic and Renaissance architectural styles. A unique feature is the Renaissance rood screen, the sole survivor in the city.

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.

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.

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
