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!

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 house of the symbolist painter has now become a museum to his life and work.

The Jewish quarter, with many small delis and shops. Lively on most days except for Saturdays.

An ancient Roman theater, the only surviving above-ground ruins of the Gallo-Roman era in Paris (ancient Lutetia, French Lutèce) apart from the nearby Thermes de Cluny. The theatre could hold approximately 15,000 spectators and measures some 132 m x 100 m. Built sometime in the 2nd century CE, the location of the actor's dressing room, the platform of the stage, and lapidary remains can still be seen. The remains were rediscovered in 1869, when new streets were being built. An excavation was subsequently ordered in 1883. The theatre has been preserved as a quiet archaeological park removed from the bustle of Parisian streets.

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

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.

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.

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

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

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.

For an interesting take on Paris, check out the underground sewers of Paris. See swords found in the sewers over the years and get an appreciation for what it takes to keep Paris running.

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.

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.

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.
