Île de la Cité lies in the very heart of Paris, separated from the rest of the city by the Seine on its own private island. Home to world-famous sites such as Notre Dame and Sainte Chapelle, it also houses a former prison… And you definitely can’t go wrong by spending at least a few hours of your time in Paris getting to know the area. Here’s a quick guide to the best things to do in Île de la Cite…

Why you must visit Île de la Cité on your next Parisian adventure

Île de la Cité is not only the physical heart of the city but also its historic one, meaning that it’s full of myths and legends. After all, it was here several millennia ago where people first chose to put down roots, leading to the city we all know and love today.

During Roman Times, the Romans set up camp close by, in the district that is now known as the Latin Quarter. Today, you can follow in the footsteps of the Romans in Paris, if only you know where to look. After all, vestiges from some two millennia ago can still be spied in various spots across the city.

Otherwise, back on Île de la Cité today, it’s worth noting that there are a plethora of hidden gems worth uncovering, not to mention some of the best-preserved medieval architecture that the city has to offer. It’s also worth noting that this arrondissement of Paris offers some excellent foodie experiences, including plenty of quaint Parisian cafés!

Best things to do in Île de la Cité (that you certainly won’t want to miss!)

Notre Dame

Notre Dame is not only one of the most iconic sites the city has to offer but also at the very heart of Paris itself. Its world-famous flying buttresses and French Gothic architecture may be what make the building so famous, but it’s definitely worth taking a peek inside the Cathedral too.

A trip inside is free, and it usually takes no more than twenty minutes to queue. There are also free daily tours in various languages, signposted outside the front of the cathedral. The magnificent cathedral is open once more after the devastating fire of 2019, though with significant modern changes.

Paris Point Zero

Paris Point Zero is the city’s true centre. Its location in the middle of the Parvis Notre Dame means that many tourists pass by, oblivious as to what lies under their feet. However, this is the point of Paris from which all other points and distances in France are measured. People often leave their change here, hoping it may bring them good luck…

Sainte Chapelle

Originally built to house some of France’s most treasured Saint relics, today Sainte Chapelle remains one of the finest preserved examples of stained glass medieval windows and architecture that France, and indeed Europe, has to offer.

Having the relics in his possession made the already Powerful French Monarchy the head of Christianity in Western Europe. This made Sainte Chapelle not just a pretty place to look at, but of vital strategic importance in the history of France.

Though the remaining French relics may now be housed in Notre Dame (notably the Crown of Thorns- though other relics were lost during the French Revolution), the two-tiered chapel is still well worth a visit. There are 15 windows in the Upper Chapel, each 15 meters high and altogether depicting 1,113 scenes from the Old and New biblical Testaments.

Though the lower Chapel (the one you first enter) was originally intended for servants, it is still more luxurious and sumptuous than most French Châteaux! If you want to visit for yourself, then you may well consider booking a ticket in advance like this one.

Conciergerie

The Conciergerie sits proud and imposing above the Seine. With turreted towers and a fancy façade, you would never guess that this building was once a former prison. In actual fact, it even housed Marie Antoinette before her execution.

Sat right next to Sainte Chapelle, the Conciergerie sits on the site of a former Merovingian Palace, and was once known as ‘Palais de la Cité’. The palace was a space for Royals right up until the 14th Century when King Charles V abandoned the Royal Residence in favour of the nearby Louvre Palace (now the largest art museum in the world).

Today, the Conciergerie contains the Hall of the Guards, the largest Gothic Hall in Europe. Visit during opening hours and you can learn all about the history of Île de la Cité, as well as the wider city of Paris, including everything there is to know about the French Revolution. Purchase your Sainte Chapelle and Conciergerie combined tickets here in advance.

Oldest Clock in Paris

The clock which many claim to be the oldest clock in Paris may or may not be the first public clock in Paris. The reason for this being is that this clock is the only one to have survived wars, revolutions and the ravages of time. There may have been others that didn’t quite manage to stand the test of time…

The clock was installed at a time when no one could afford their own clocks and wristwatches hadn’t even been invented yet, let alone mobile phones. Erected for the benefit of the public, the clock enabled Parisians to know when shops should be opened and closed.

The clock has been cleaned and restored a number of times throughout its life. The first time was in the 1500s, while its most recent clean was in 2012. The bell that chimes isn’t original as that one was melted down during the French Revolution. Nevertheless, I’m pretty sure that it’s safe to say that in some respects, this little corner of the city has stood still for millennia!

The adjacent road, lying by the Seine, ‘Quai de l’Horloge‘ is even so-called because of this iconic clock. So next time you’re walking along Boulevard du Paris, make sure to look up as you might just spot this 1370s masterpiece…

Flower Market (Marche aux Fleurs et aux Oiseaux)

A little over the road, close to the Conciergerie and the Oldest Clock in Paris, you’ll find the iconic Île de la Cité flower market. Here you can pick up whatever flowers happen to be in bloom during your visit to Paris (my personal favourite are all of the varying types of peonies that look like paper and smell simply divine…)

Founded as early as 1808, the market has attracted visitors ever since with its colourful displays and dazzling array of plants and flowers. In times gone by, the market would have sold plants and birds, meaning that it was once called the Marché aux Fleurs et aux Oiseaux.

Today, many of the stalls are held in Green Pavilions which were first installed in 1900. The Flower market is free to visit and open every day asides from Monday.

Rue Chanoinesse

If you’re looking for a glimpse of medieval Paris, then look no further than Rue Chanoinesse. With fewer tourists than the rest of the area, views onto Notre Dame and some of the best eateries the area has to offer, it’s definitely worth leaving the beaten track of Parvis de Notre Dame to check out this wonderfully preserved street.

The street was once home to an order of Monks, who are partially responsible for the preservation of this medieval Snapshot. Rue Chanoinesse is also home to sights such as the Gravestone Courtyard of Paris, the cutest Café in the city and a passage to one of the narrowest streets the city has to offer. The street is also associated with the affaire de la rue des Marmousets.

Gravestone Courtyard

It would seem that you are never far from the macabre in Paris. And even the quaint street of Rue Chanoinesse has its own dark past. Situated between two bars, you’ll find a lovely maroon door.

However enter it (the courtyard is private and its hard to gain access unless you’re ‘in the know’), and you’ll find another side of Paris. For, lying on the floor, you’ll find the remains of gravestones.

Slightly worn, you can barely make out much of the gothic script which must have once covered the entire floor. The Gravestone Courtyard is paved with grave markings taken from an 18th-century church which was demolished during the grand Haussmann architectural reforms in the 19th- century.

Au Vieux Paris d’Arcole

Quite possibly the cutest café in Paris, Au Vieux Paris d’Arcole is covered in wisteria and Oh so Parisian. Stop here to enjoy a coffee (or even a glass of French wine). I’m told the food here is particularly good (one of my closest friends even chose this spot for her Valentine’s Day meal).

Hôtel Dieu

The oldest hospital in Paris can be found steps away from Notre Dame Cathedral and dates back many centuries. But what many visitors to the 4th arrondissement of the city don’t know is that you can actually visit the interior courtyard of this building for free! Filled with beautiful arches and a secret garden, it’s a great escape from the hustle and bustle of the nearby Parvis Notre Dame.

I first visited a couple of years ago with a now-ex-boyfriend in tow and was pretty impressed with what I discovered inside!. At the time, it was unclear as to whether you were allowed to visit or not. However, a large plaque on the grand entrance’s exterior now declares that visitors are welcome!

Once inside, there’s plenty of Italianate Gardens and 19th-century architecture to admire. From twisting staircases to long galleries, there are countless photo angles to capture and it’s a great escape from the crowds which inevitably flock to the area to see Notre Dame.

Have a picnic in Square du Vert-Galant

Situated directly below Pont Neuf, the pretty Parisian park of Square du Vert-Galant was actually derived from the quays which were needed to anchor the stone bridge in place. Named ‘green gallant’ for Henry IV, the space is perfect for a picnic during the summer months.

My girlfriends and I often joke that the weeping willow which presides over the park is the ‘perfect spot for a first kiss’. This spot can be found on the most westerly tip of Île de la Cité and is easily one of the best parks in the entirety of Paris.

Discover the Paris bouquinistes

Due to the abundance of green stalls lining both banks of the Seine, it’s often said that the well-known river “runs between two bookshelves“. So iconic is this scene, that in 1991, the Paris bouquinistes were made a UNESCO world heritage site.

Relax in Square Jean XXIII

One of the most tranquil spots in the city is actually where visitors would least expect. Square Jean XXIII can be found lying in the shadow of Notre Dame, the illustrious Gothic Church that is so iconic that it has since become one of the symbols for Paris itself.

The park is home to beautiful cherry blossoms in the spring and is a beautiful place to relax all year ’round. Please note that, unfortunately, due to the terrible fire at Notre Dame in 2019, the park is closed until, further notice.

Best hidden gems of Île de la Cité

4 Rue de la Colombe

One of the more unusual love tales to emerge from the Middle Ages is that of the colombes, or ‘doves’ as they are known in English. The story goes that in the 13th-century, there lived two doves. At the time, one of the sculptors working at nearby Notre Dame Cathedral was residing in No. 4.

The man was originally from Brittany and he resided together with his two doves (a male and a female). That was until a Parisian flood caused the building to collapse. Although only the male dove escaped the rubble, he would return on a daily basis with food and water to feed his lover.

While she eventually managed to escape, locals were so touched by the story that the myth was carried on down the generations. Strangely enough, records show for certain that the house was rebuilt in 1297 making the tale that much more probable…

5 Rue de la Colombe

Nearby, on the road by No5., you’ll find one of the few vestiges of Roman Paris (or Lutetia as it was then called) that can still be spied in the French capital today. After all, it’s here where you can see a small piece of the Roman defences that existed on Île de La Cité centuries ago. The wall was rediscovered in 1898.

Heloïse & Abelard’s House

Fated lovers Abelard and Heloïse are now alleged to be resting in Père Lachaise Cemetery, the largest and oldest graveyard in the City of Light. A couple who lived during the Middle Ages, Heloïse was the niece of .a Canon of the Cathedral while Abelard was her tutor and many years her senior.

Heloise soon fell pregnant and the couple wed in private. Alas, they were forcibly separated and never saw each other again. Today, there is much debate as to the true story behind these two very real people.

Although Abelard and Heloise never saw each other again, though they corresponded through letters several times over the years. As per the legend, it’s alleged that the couple lived together in the place where a plaque can now be seen.

Rue des Chantres

One of the narrowest streets in the city can be found in the form of Rue des Chantres. Narrow, dark, and leading between Rue Chanoinesse and the Seine, one highlight of this road is a little plaque at the end of the road which announces the height of the 1910 great floods of the city.

Fake Medieval doorway, 1-3 Rue des Ursins

At first glance, the beautifully carved wooden door at 1-3 Rue des Ursins appears as if it wouldn’t look out of place upon one of the great medieval mansions of Le Marais.

However, look at the building a little more closely, and it soon becomes apparent that the construction is much more modern. As it turns out, the placement of the door only dates back to 1958, though the materials are much older!

Rue Massillon

For the very best view of Notre Dame without the crowds, you need to head just a few metres off the beaten tourist track. For, Rue Massillon connects massively popular Rue Cloître du Notre Dame (i.e. one of the avenues which run alongside the ecclesiastical building) and Rue Chaoinesse.

Once part of the long-destroyed cloisters of Notre Dame, this road was created in the 19th-century, although several buildings date back to the 17th and 18th centuries. However, what is particularly notable about this secret spot on Île de la Cité is its particularly impressive view of Notre Dame!

Spy Wallace Fountains

The Wallace Fountains of Paris are as essential to the landscape of Parisian architecture as the Arc de Triomphe but are often not thought of as such. These fountains date back to the latter half of the 19th-century and were originally installed so as to ensure that all inhabitants of the city had access to fresh water.

Though some water fountains are located in parks which have open and closing hours, other fountains can be found along the side of the street, including in several spots across Île de la Cité. Today, over there are still over a hundred Wallace Fountains still in existence in Paris.

Discover the gargoyles of Notre Dame

Setting the striking two towers and flying buttresses aside, there is perhaps no architectural feature quite as synonymous with Notre Dame Cathedral, in the heart of Île de la Cité in Paris as those of the gargoyles.

The French architect Eugène Emmanuel Viollet-le-Duc oversaw a mid 19th-century refurbishment of the Cathedral over a period of 25 years and wanted to emanate medieval architecture. This is when the great spire was added, as well as some of the most dramatic grotesques (another term for gargoyles). To discover more about this period of history for Île de la Cité, check out our guide to the Notre Dame Gargoyles.

Where to stay in Île de la Cité

Though Île de la Cité itself has limited options for places to stay, you can instead opt to stay on the other natural Seine Island that overlooks Île de la Cité and is a light stroll away over a small bridge. One of the more luxurious options on Île Saint Louis is that of the Hôtel du Jeu de Paume, which is a four-star well-reviewed hotel.

Amenities of the hotel include perks such as free Wifi, air-conditioned rooms, and hardwood floors. What’s more is that this hotel also offers apartment rooms which boast their own kitchenette and seating areas, giving you the opportunity to enjoy more of a local’s experience while in the city.
