Musée de la Serrure

Its exhibits come from such diverse origins as ancient Egypt, classical Greece and the Roman Empire, medieval Europe, and Napoleonic France, but controversially including many items that were looted from their places of origin. Its most famous exhibit, of course, is Leonardo da Vinci's painting of the Mona Lisa (French: La Joconde, Italian: La Gioconda), generally to be found surrounded by hordes of camera-flashing tourists. The Louvre poses many of the same challenges to the visitor as Paris itself; overwhelming in size, crowded in high seasons, and much information available only in French. If you want to see everything in the Louvre, plan at least two full days. However, it is better to pick and choose, as the collection was assembled with an eye to completeness rather than quality. As of July 2019, due to intense crowding and reports of ticket fraud, entry now almost always requires a pre-booked timed ticket, even for holders of the Paris Museum Pass.

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.

The massive parish church of the Les Halles area is a notable example of late Gothic interspersed with Renaissance details (including the entire front façade), as it was only completed in the 17th century. Its unique form results from a combination of relatively short length and impressive height of over 30 metres inside. The latter allows room not only for an array of stained glass windows and paintings, but also France's largest church organ of 8,000 pipes. The sculpture Écoute, depicting an oversized human head, was placed in front of the church's southern facade and has become a favourite photo spot.

One of the best-known and most beautiful churches in Paris, in the guise of a Corinthian order classical temple. Construction started in 1764, although the church was not finally consecrated until 1845. The Madeleine has a lavish interior of marble and gold.

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

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

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.

An industrial design museum in Paris that houses the collection of the Conservatoire National des Arts et Métiers (National Conservatory of Arts and Industry), which was founded in 1794 as a repository for the preservation of scientific instruments and inventions.

The national library preserves collections of historic documents of both French and international origin. It holds 5,000 Greek manuscripts. You can get a day pass to visit or choose to visit only the expositions the library hosts.

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.

A Gothic church tower in a square 150m to the west of the Hôtel de Ville was restored by Ballu, is all that remains of Eglise Saint-Jacques-de-la-Boucherie, which was the meeting place in Paris for pilgrims heading to Santiago de Compestela. As such it is included on the UNESCO World Heritage List as part of the Routes of Santiago de Compostela in France.

Many feel that this, Paris' town hall, is one of the loveliest buildings in the city. You might not get that from the front view, but try watching the light change on its roofs and towers during sunset from one of the cafés on the Ile de St. Louis, the Lutece for instance. Alternatively, go to the top floor of the Bazar de l'Hôtel de Ville (BHV) department store opposite, on rue de Rivoli and walk up a flight of stairs to the roof terrace (terrasse), from which there is a dramatic view of both the roof of the Hôtel de Ville and the immediate surroundings and river. The present Hôtel de Ville replaced the 16th century original which was burned down during the Commune in 1871. A pastiche of its predecessor, but on a far larger scale, it was designed by the architects Ballu and Deperthes, chosen after a competition, and was mostly completed by 1882. The building is lavishly, and some would say heavy-handedly, decorated both inside and out, and finished in an arrestingly white stone, similar to that used for the even more eye-catching Sacre-Coeur basilica. The statue on the garden wall on the south side is of Etienne Marcel, the most famous holder of the post of "prevôt des marchands" (provost of merchants) which pre-dated the office of mayor. Marcel came to a sticky end, lynched in 1358 by an angry mob after trying to assert the city's powers a little too energetically. The Hôtel de Ville was for many years the private fiefdom of Jacques Chirac, France's president before Sarkozy, and was the site of a scandal centring on both illegal jobs given to Chirac's party members and an immense entertainment budget. General de Gaulle greeted the crowds from a front window in 1944 when Paris was liberated from the Germans and Robespierre was shot in the jaw and arrested in the original building in 1794. Admirers of Hôtel de Ville's architecture will want to know that Ballu also built the Church of La Trinité in the 9th arrondissement and the belfry of the town hall of the 1st arrondissement, opposite the Louvre's east façade. Ballu also restored the Tour St Jacques (see below), which was uncovered after restoration work lasting over a decade.

It was conceived by Louis XV as a grand neo-classical church honouring St. Geneviève, the patron saint of Paris. After the Revolution, the building was converted into a mausoleum for the great philosophers, military, artists, scientists, and heroes of the French Republic. Occupants of the crypt include Voltaire, Rousseau, Victor Hugo, Zola, the Curies, and Alexandre Dumas (reinterred here in 2002). The view from the dome (206 steps) is marvellous. Check tour departure times at the information desk. A fascinating reconstruction of Foucault's pendulum also hangs within the Panthéon.

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.

The Musée Grévin is a waxwork museum with some 500 characters arranged in scenes from the history of France and modern life.

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.

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.

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.
