Pont Alexandre III

Once the dye works for royalty, it is now a museum.

If you were a city planner in one of the great cities of our Earth and you discovered that a railroad right-of-way had been abandoned and would never be used again what might you do? Perhaps if you knew your stuff you'd convert it into a 4 mile long park, about half of which is elevated above street level on the old rail viaduct. This long narrow park pretty much allows the visitor to walk in carfree bliss from Place de Bastille to the Bois de Vincennes.

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

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.

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

Between the River Seine and the rail yards attached to Gare de Lyon and Gare de Bercy is a green space which would seem pretty huge if the 12th weren't also the home of the Bois de Vincennes. The park is a good place to hang out waiting for the line to form for sporting events and concerts at AccorHotels Arena.

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.

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.

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.

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.

Two-level bridge.

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.

The ancient medieval fortress and prison of the city's island, site of some remarkable medieval royal architecture and the scene of Marie Antoinette's imprisonment in the period leading to her execution in 1793; lots of revolutionary associations.

Built in 1717, the windmill is now part of a restaurant of the same name, and is easily visible from the street.

The largest square in Paris with fantastic vistas in every direction. It was in this square (then called la Place de la Revolution) that the French King Louis XVI, Marie Antoinette and many others were guillotined during the Terror. The large Egyptian obelisk in the centre of the Place de la Concorde was brought from the Temple of Luxor.

An indoor sports arena that seats around 17,000 for sports and slightly over 20,000 for major concerts; formerly known as Palais des Omnisports de Paris-Bercy and Bercy Arena. Home to numerous concerts and major sporting events, most notably the Paris Masters tournament on the ATP World Tour in men's tennis.

17th century church.

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

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!
