Saint-Germain l'Auxerrois

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.

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.

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.

Private collection of French, Italian, Dutch masterpieces in a typical XIXth century mansion.

A must for anyone interested in the history of the American Revolution. This small cemetery includes three mass graves from the French Revolution, plus a section that includes many of France's most noble families that lost members during the French Revolution and consequently have a continuing right to be buried there. In the farthest right hand corner is the tomb of General Lafayette, the friend and fellow soldier of George Washington. Beside him is his beloved wife plus other members of her family, the de Noailles, who were almost completely wiped out during the French Revolution because of their closeness to the Court. Since 1834 the American flag has apparently flown continuously over his grave, even during the German occupation of Paris during World War II. Well worthy of a visit.

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.

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.

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.

Try to visit the cabinet des Médailles.

There are a number of famous occupants, but the real reason to visit this cemetery is to see the ornate tombstones, sculptures, and other sometimes macabre, sometimes touching memorials Parisians have left here for their dead.

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.

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.

Built adjoining the now-lost royal palace of the Tuileries, these gardens lying immediately west of the Louvre offer a central open space for Parisians and visitors with semi-formal gardens (an outdoor gallery for modern sculpture), various cafés, ice cream and crépe stalls, and a summer fun fair. The gardens are frequently home to a giant Ferris wheel and enclose the Musée de la Orangerie and the Jeu de Paume.

The burial place of existentialist philosopher Jean-Paul Sartre, feminist Simone de Beauvoir (both of whom lived nearby); musician Serge Gainsbourg; artist Man Ray; the poets Charles Baudelaire, Guy de Maupassant, Charles Sainte-Beuve, and Marguerite Duras; the founders of the Theatre of the Absurd Samuel Becket and Eugene Ionesco; the sculptors Constantin Brancusi and Ossip Zadkine; the composers Camille de Saint-Saens and César Franck; the actors Maria Montez and Jean Seberg; the French officer Alfred Dreyfus; the founder of the Larousse encyclopedia, Pierre Larousse; the industrialist André Citroen, and many others.

Established in 1926, it was meant to show appreciation for Muslim help in fighting the Germans. The café serves excellent mint tea and North African food.

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.

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.

The Pasteur Museum is housed in the apartment where the great scientist spent the last 7 years of his life. Hardly touched since that time, the museum is full of personal memorabilia and scientific instruments. Pasteur is buried on the grounds in a flamboyant mosaic-decorated mausoleum. The museum was closed to individual visitors for security reasons after the 13th November 2015 Paris terrorist attacks.
