Saint-Nicolas-du-Chardonnet

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.

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.

For many visitors one of the must-see places in Paris is the Avenue des Champs-Elysées which was first created in 1667 by Louis XIV's gardener, Andre Le Nôtre, in order to improve the view from the Tuileries garden. This elegant and broad avenue was extended towards the end of the 18th century, now running from the place de la Concorde to the Arc de Triomphe. It is noted today as one of the most prestigious shopping boulevards of Paris.

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).

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.

A sculpture by Auguste Rodin in memory of the French novelist Honoré Balzac. The artwork is sometimes considered the first truly modern sculpture.

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.

One of the last remnants of medieval Paris outside of the 4th, this tower was once part of a castle called l'hôtel de Bourgogne.

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.
