In all the years I've been visiting the chateaux of Loire Valley, I've loved the furnishings and gardens, but what I've loved even more are the stories, the scandals and the legends attached to their history.
Renaissance rulers may not have had social media, but they were skilled at documenting their lives: hidden sculptures, secret letters and double entendres all served to keep stories alive down the centuries. This was especially true along the secretive shores of the Loire Valley, France.
We know a lot about the shenanigans that took place behind closed doors in the fairy tale French chateaux of the Loire. Just stepping inside one is already an invitation to mystery.
I'd like to thank those who centuries ago took the time to gossip and record everyone else's (and sometimes their own) indiscretions so that the rest of us might witness a snippet of the unsaid, the less savory or the downright scandalous.

There are more than 300 Loire Valley castles and from my perspective, each is worth visiting. Today, however, we will focus on four of the most famous castles in France: Welcome to Blois, Chambord, Chenonceau and Amboise, all of which are part of what is known as the "Loire Valley UNESCO World Heritage Site".
You might consider doing the same if this is your first visit.
Contrary to popular belief, not all (or even most!) French châteaux are in the Loire Valley: they're everywhere! From the castle of the Dukes of Brittany in Nantes to the atypical Château de Bussy-Rabutin in the depths of Burgundy to the Cathar fortresses in the Southwest, it's hard to go more than a few kilometers in France without a castle waving in the distance.
Seven kings and ten queens lived in this castle a stone's throw from the Loire River, plenty enough to create a significant amount of mayhem.
It was the late 1500s and France was being torn apart by religious wars. The Duc de Guise, a charming fellow, was much loved and respected for his (ultra)staunch catholicism. One could say he was more popular than Henri III, France's king at the time.
That did not please the king, who would play second fiddle to no one and who, unable to dampen the Duc de Guise's popularity or bring him to justice, resorted to that frequent royal fallback: murder.
On the Friday before Christmas in 1588, the duke was summoned to the king's bedroom in the Chateau de Blois. He had been secretly warned his life was in danger but his ego was greater than his fear and so, when summoned, he went.
The king's bodyguards awaited in the entrance and once the duke entered, they locked the door and attacked him, stabbing him multiple times until he died.
Meanwhile the king had bravely taken refuge out of sight.
In the end, this did the king little good. No one rallied to his side, he was reviled and eventually excommunicated, and finally was assassinated a few months later. What goes around comes around.
Usually, when you go to a chateau, you go to a chateau. One.
But when you come to Blois, you'll actually be visiting four chateaux, because it is made up of four distinct wings, built at different times, by different kings.
This is the oldest, from the 9th century, in the early days when Blois was built as a fortress. All that is left from this wing is a tower and the Grand State Hall (the oldest of its kind in France) where the États Généraux met — the parliaments of noblemen.
Next came the pure French-style Gothic castle and its iconic colonnaded gallery which lines the ground floor. You can see Louis XII on horseback in a sculpture sitting in a niche on the façade.
The Italian influence is now obvious, the result of François I's incursions into Italy.
Blois at this point is becoming a Renaissance palace, with its circular staircase and balconies fashioned after those of the Vatican. That staircase, by the way, looks a bit lopsided but it was once in the center of the building. It seems part of the building was nibbled away by Gaston d'Orléans and his own architectural and building plans...
The newest and final wing was built in the Classical style by Gaston d'Orléans, Louis XIII's brother. He was going to be King of France since his brother had no heirs so he began adding furiously to Blois, wanting to build an entirely new chateau. He got as far as the first wing but had to stop when the future Louis XIV was born.
Not only was poor Gaston shoved out as chief royal, but his funding dried up as well. Before he quit Blois, he did create a magnificent garden with more than 2000 plant species, which sadly no longer exists.
The chateau eventually fell into disrepair, and only escaped destruction during the French Revolution because it was given over to the army.
Catherine was Francois I's daughter-in-law, married to his son, Henri II (more about him and his love triangle when we reach Chenonceau, below). She was also extremely superstitious.
She often visited Blois with her children (which included three future kings) and of course had her astrologer, Cosimo Ruggieri, with her.
To help him observe the stars, which he needed for his horoscopes, she built him an observatory in the still-standing medieval fortress tower. She often spent time up there with him, discussing her and her children's futures.
She also had a more ominous reputation — that of murderous queen and poison expert. We'll never know if that was true but her enemies did seem to die conveniently.
This cabinet is also said to contain hundreds of secret drawers in which, if legend were to be believed, she would have hidden her deadly little vials.
WHAT IF YOU DON'T HAVE A CAR?
A number of Loire Valley chateaux - including several of these - CAN be reached without a car by using public transportation, mostly trains. So don't let transport keep you away!
Delightful Chenonceau! All too often, when you ask someone for their favorite Loire château, this is it!
And no wonder... with its romantic history, gorgeous interior or delicate arches over the River Cher, how can you not sigh?
Yet this little gem has a more sinister history, one that includes jealousy, friendship and revenge.
Chenonceau is perhaps most famous for the power struggle between Diane de Poitiers (Henri II's mistress) and Catherine of Medici (his wife).
Diane de Poitiers had assisted in Henri II's birth and was eventually entrusted with his education. When he was a child of seven, Henri and his brother were sent off to Spain as a hostage in exchange for their father's freedom (I tell the full story of this dreadful exchange on Substack).
She may have kissed him goodbye on the forehead, or so the story goes, one of the few gestures of affection he received on his way to exile. And, according to legend, he would never have forgotten.
Upon his return to France, Henri was 11. Diane was 31, and faithfully married. But then her husband died, and Henri grew up, and things happened.
Henri II, as he had become, was destined to marry Catherine de Medici, and the moment she arrived at the French court, she realized he only had eyes for "the other woman", Diane (who also happened to be her third cousin).
When Henri II inherited the spectacular Chenonceau in 1547, he promptly gave it to Diane.
His wife Catherine was not amused. She had loved this chateau and had designs on it herself. But things were as they were in those days and she would have to bide her time...
Meantime, Diane beautified the gardens and built a wooden bridge linking the two shores of the river Cher so she could go hunting more easily on the other side.
While Diane enjoyed the castle of her dreams, it wouldn't be hers forever.
One day, Henri decided to joust at a wedding, wishing to show off his prowess (he was 40) to his mistress. His superstitious wife, watching anxiously from the audience, had a premonition and begged him not to joust. Henri went ahead, caught a lance in his eye, and soon died.
DIANE'S REPUTED BEAUTY
By all accounts, Diane de Poitiers was a beauty.
When Henri died, she was 60 years old, and still beautiful, stunning even.
How did she do it?
She went to bed at 8pm and rose at dawn, starting each day with an ice cold bath in the River Cher. She would sneak out to bathe through a small staircase used by delivery men to ferry produce along the river to the chateau.
She also ate well, rode a lot, avoided the sun and used little makeup, no mean feat in this era of heavy face paint. Quite the modern woman, it seems.
It was a strange ménage à trois, where everyone knew one another's role and while it was far from ideal, they all made do with it.
Henri wanted his mistress, Catherine wanted children (which required Henri's cooperation) and grudgingly accepted his liaison.
Diane, for her part, wanted to keep the peace and encouraged Henri to sleep with his wife. Between his wife and his mistress, Henri would be too busy to wander elsewhere. It worked. Catherine had plenty of children, and Diane remained Henri's mistress until his death.
Catherine would finally recover Chenonceau at Henri's death in 1559, swapping it with Diane for Chaumont-sur-Loire (which some claim was a better deal for Diane, as it brought in more income).
Catherine put her indelible stamp on Chenonceau: she redecorated, upgraded the façade, added stained glass windows, and put a roof over the once modest wooden bridge on the river — now known as the Gallery.
One day, now happily ensconced in Chenonceau, Catherine decided to throw her son Henri III (who had become king after his brother Henri II died) a birthday party. This was a time of high tension between Catholics and Protestants and she needed a show of power.
Remember, she was from Tuscany, from Florence in fact, a city steeped in art and invention. So she commissioned one of her countrymen to come up with some majestic entertainment and decked the gardens with every possible column, statue or obelisk they could find.
But the crowning glory designed by her Italian artist would be... a night sky illuminated by France's first-ever fireworks.
Given her Tuscan origins, Catherine had brought with her to France memories of fresh fruit and vegetables the likes of which hadn't been seen much around here. Once Chenonceau was firmly in her grip, she began to plant... and plant...
Her Italian gardeners made sure her olive and citrus trees stayed healthy, and she planted artichokes and asparagus, vines and broccoli. She introduced a mysterious vegetable that had arrived from the New World with Christopher Columbus: the string bean.
She also introduced sherbets and fruit pastes, bringing the sunshine of Tuscan cuisine into the more northerly regions of the Loire.
And perhaps most noteworthy, she introduced a magical eating implement to the court: the fork.
Visiting Chenonceau is a delightful experience but you won't get to see it all: some parts are hidden.
If you were to follow (it is closed to the public) the stairway up to the combles, the attic, you would come to an indoor drawbridge that once protected an unusual venue: a private convent for nuns.
When Henri III was murdered (after having ordered the murder of the Duc de Guise, if you recall), his pious wife, Louise of Lorraine, decided to mourn at Chenonceau.
She had hoped to start a community of Capucin nuns there but died before doing so. In her will, she left some money to her brother for this very purpose. Then he died, and the wish passed on to his wife, Marie of Luxembourg, who would eventually act on it.
She brought a modest community of nuns to the small attic at Chenonceau, their virtue protected by said drawbridge.
They would stay a few years before moving on to larger quarters in the city of Tours, and the drawbridge would close behind them, closing off their secrets forever.
Not all of Chenonceau's mysteries are that old: the chateau played a secret role as recently as World War II.
The castle's position linking two shores of a river made it ideal for wartime comings and goings: it so happened that one side of it was in occupied France and the other in (so-called) Free France.
Refugees from the Nazi-occupied shore could transit through Chenonceau in the dead of night on their way to freedom.
With the help of the Menier family, who had owned the castle since before World War I, the Resistance was able to spirit countless refugees across the River Cher.
Speaking of World War I, Chenonceau also played its part during that war. It was transformed into a field hospital and over the course of the war treated more than 2000 wounded.
We know and love Chambord, that jewel of the French Renaissance and one of the most famous landmarks of France... its 426 rooms, 77 staircases and 282 chimneys and its fenced park, Europe's largest enclosed forest.
We know it was built on a swamp as a hunting lodge for François I, and that he only spent 72 nights there in his 32 years as king of France (1515-1547).
What we may not know are the oddities hidden behind Chambord.
François I was a bit of a show-off. Why else would he build all these royal buildings and hardly bother with some of them afterwards?
He had returned from his Italian campaigns filled with wonder at the art of the Italian Renaissance, and wanted something grandiose. And newly discovered riches in the Americas promised a rosy financial future.
Despite his building frenzy, you can't say François I was particularly profligate when it came to his royal dwellings. In fact, he spent about 1% of the national budget on buildings, not particularly exorbitant.
The double helix stairway is one of Chambord's most famous attractions.
Most historians believe its design was strongly influenced by Leonardo da Vinci, who spent the last three years of his life in the Loire Valley, in Amboise.
His drawings show similar stairways, some with quadruple stairs, so even though he died before Chambord was built, there is a strong likelihood that at the very least his ideas were involved.
Here's what Alfred de Vigny, the French Romantic poet, had to say about the double helix stairway:
"The base of this strange monument is, like the monument itself, full of elegance and mystery; it is a double stairway that rises in two interlocking spirals from the deepest recesses of the edifice to above the highest bell tower, to end with a lantern or opening, crowned with a colossal lily visible from far away; two men can ascend simultaneously without seeing one another."
It may feel childish but I defy you to visit Chambord and not try the experience for yourself.
The utter impracticality of Chambord makes you wonder why such an insane building was ever created. Some of the rooms measure more than 100 m² and were clearly never meant to be lived in; heating them would have been impossible — I say this with confidence, having once visited in a freezing February.
And yet the place is thick with symbolism, which suggests it was more than just a royal hunting stop.
Consider the salamander, François I’s emblem. You see it elsewhere, but nowhere as relentlessly as in Chambord. It’s carved into doors and mantelpieces, painted onto ceilings and lintels — and not one is identical to another. It’s as if the king were telling a story through those salamanders: good government here, personal virtue there.
Some people believe the symbols carry a deeper, more esoteric meaning. The salamander itself has occult connotations. The number eight — traditionally associated with peace — appears everywhere in the château. Crowns are carved into the stone, referencing previous kings. The staircase in the lantern tower leads nowhere.
Religion, too, was central to François’s worldview: several royal monograms were deliberately printed in reverse, “so that God above could read the power of the king”.
So while the secrets of Chambord have never been fully cracked, their presence is unmistakable.
As you wander through the château, use your sixth sense — you never know what it might reveal.
Louis XIV, whose reign started about a century after François' death, would spend a lot more time in Chambord than his distant relative (Louis was a member of another branch of the family — royal successions in France are nothing if not complicated). Chambord was so big he had room numbers assigned so he would not get lost.
Chambord fared poorly during the French Revolution.
The park's animals were slaughtered, whatever furniture remained was stolen, and some revolutionaries went so far as to call for the razing of such a symbol of "megalomaniacal monarch" and replacing it with modest lodgings.
Fortunately they did not succeed.
Yes, we know it lives in the Louvre BUT — once upon a time...
Like Chenonceau, Chambord did its patriotic duty during World War II. As the Nazis marched towards Paris, authorities feared (with reason) that works of art would be looted.
With the capital under threat, the major museums decided to organize what would become the greatest relocation of paintings in history: on 28 August 1939, some 5500 crates arrived at Chambord.
Their priceless contents included the Mona Lisa (she would only stay a few months and move on to another location).
Chambord became the processing and storage center for the paintings: it closed its doors to the public and scores of art experts stood guard over artistic treasures, to keep them safe but also to make sure they weren't damaged by humidity or insects.
The paintings made it through the war and were returned to their official locations.
The best way to approach Amboise is on foot, crossing the bridge over the Loire.
From the moment you catch sight of it, your eyes will gravitate automatically towards this imposing structure, however hard you try to look away. It dominates the city and unveils itself the closer you get.
The original chateau was built in the 5th century but obviously it was much improved over time.
By the 16th century, it had become one of royalty's favorite residences.
While royal children were often born at Blois, they were soon sent to Amboise for their early education. Its position atop a hill made it easy to protect the royal offspring from such dangers as escape, war, kidnapping or epidemics.
That said, they received an excellent education here, not only in languages (Greek and Latin as well as Italian and Spanish) but also science, sports and the jeu de paume, the forerunner of tennis. Along with a retinue of servants to make sure they stayed healthy and became wise...
Part of the mysterious charm of Amboise, at least for me, is that it is two chateaux in one: on the left, you can see it as an urban fortress, protecting the town below but on the right, seen from the rear, it is a bucolic rural retreat, filled with romance. It all depends on where you're standing.
This Tuscan genius spent the last three years of his life in France, at the request of François I.
Just try to imagine this "old" man (he would have been 64 at the time), riding his mule all the way from Italy and pulling a cart filled with his belongings, including drawings, and plans, and a few of his favorite paintings. One of these bore the smiling face of a woman — the Mona Lisa.
The king would house Leonardo nearby in what is now the Clos Lucé (his studio is still on display) and would go back and forth from Amboise, a few minutes away, through its many underground passageways.
When da Vinci died in 1519, he asked to be buried at Amboise and a chapel is dedicated to him right outside the castle.
For centuries, it was believed that François I held Leonardo in his arms as he died, a story that was embellished over time and even made it into several paintings.
In fact, Leonardo's assistant traveled to Paris to tell François his protégé had died. The letter he carried to the king was only made public in the 19th century, revealing the king had been nowhere near the artist at his death.
So you see, we're certainly not the first to disseminate fake news...
Twenty years earlier, in 1498, another famous death had taken place at Amboise: that of King Charles VIII of France. It was a senseless accident.
Charles was on horseback, heading with his wife, Anne of Brittany, to watch a game of jeu de paume, when he smashed his forehead against the stone lintel of a door. He recovered, went on to watch the game, even spoke to a few people but then started becoming disoriented. He agonized for nine hours before dying. He was 28 years old.
Some of the doorways in Amboise may have been built low on purpose to help the castle's residents flee attack.
Galloping off on a horse, a rider could simply bend down and squeeze through, something much harder to do by someone in mad pursuit wearing an armour. Perhaps Charles was distracted by the upcoming game and simply had not paid attention to the door...
Amboise is particularly well-known for its subterranean labyrinths and its ingenious passageways.
Like many castles of its time, it required supreme organization, with many servants and guards running here and there to attend to the most minute royal needs.
A warren of tunnels linked the different parts of the castle, and many were used for such events as the changing of the guard, or as living quarters, or the medieval equivalent of a staff cafeteria, the Salle des Lys.
Most impressive is the 40-meter Tour des Minimes, which has the peculiarity of being wide enough to allow a horse carriage to ascend a gentle slope and enter the castle courtyard without passengers having to set foot on the ground.
It is also quite ingenious for its lighting, which enters the well-like structure through openings along the side and top, giving it the impression of a cathedral lit by candlelight.
After Amboise fell into royal disuse, as castles do when a better place appears, the tower was turned into a jail. You can tell by the graffiti carved into its walls.
All four of these chateaux would be beautiful and worth visiting even without such fascinating stories, but knowing about the marriages, infidelities, murders and other secrets make them even more enticing.
While these four are fascinating, you'll also find intriguing stories nearby at Cheverny and Chinon.
And if you happen to be here at Christmas, the Loire Valley goes all in, decking its castles in amazing lights and decor for the occasion.
Finally, if you don't have a car, here's how you can reach the main chateaux of the region by train.
How many chateaux are there in the Loire Valley?
There are over 300 châteaux in the Loire Valley, ranging from grand royal palaces to fortified medieval castles.
What are the best chateaux to see in the Loire Valley?
Some of the best Loire Valley chateaux include Chambord (for scale and architecture), Chenonceau (for elegance and its bridge over the Cher River), Villandry (for its gardens), Azay-le-Rideau (for its perfect Renaissance proportions), and Amboise (for its royal history and Leonardo da Vinci connection).
If you have time to see only one chateau in the Loire Valley, which should you visit?
If you can see only one château in the Loire Valley, consider the Château de Chenonceau for its unique combination of beauty, riverside setting and rich historical associations.
What is the best time of the year to visit the Loire Valley in France?
The best time to visit the Loire Valley is during the shoulder season. That would be spring (April to June) and early autumn (September to October). The weather is mild and gardens are in bloom or at harvest. As a bonus, the châteaux are less crowded.
What is the best town to use as a home base when visiting the Loire Valley in France?
Several cities come to mind if you want to focus on the best-known chateaux, those in the eastern Loire Valley:
Amboise has a walkable town center and great train connections, with easy access by car to Chenonceau, Chambord, Chaumont-sur-Loire, Blois, Clos Lucé, Villandry – and Amboise, of course.
Tours is a larger city, and perfect if you're using public transport and want restaurants and markets. From here you can reach Villandry, Azay-le-Rideau, Amboise, Langeais, and Chinon.
Blois is also a great base, home to Blois castle and with easy access (by car or shuttle) to Chambord, Cheverny and Chaumont-sur-Loire.
