    Mona Lisa: Respect, Fame, and Safe Behind Glass

    From Leonardo da Vinci’s Florence in 1503 to the bulletproof glass of the Louvre, follow the extraordinary fate of the Mona Lisa. Discover how a Renaissance portrait became the ultimate icon of world art: through royal ownership, the sensational theft of 1911, Dada and Pop Art appropriations, international tours and the constant challenges of high security.

    Florence: Leonardo works on the portrait of Lisa del Giocondo

    Basilica of the Santissima Annunziata, Piazza della Santissima Annunziata, Florence, Italy

    A marginal note in a book, written by Agostino Vespucci in October 1503 and rediscovered in Heidelberg in 2005, proves that Leonardo da Vinci was working on a portrait of Lisa del Giocondo at that time.

    The painting was not finished in one season: Leonardo would retouch it for years, perhaps until 1516-1517.

    Death of Leonardo in Amboise: the painting enters the royal collections

    Château du Clos Lucé, 2 rue du Clos Lucé, Amboise, France

    Invited by Francis I in 1516, Leonardo brought the Mona Lisa with him, according to tradition. He died at the Clos Lucé on May 2, 1519.

    The painting then entered the French royal collections, where it would remain for three centuries before becoming a national asset.

    The Louvre exhibits it permanently: a national asset

    Louvre Museum, rue de Rivoli, Paris, France

    Since 1797, the Mona Lisa has been on permanent display at the Louvre. The painting's status changed: it no longer belonged to the king, but to the nation.

    A brief stay in Napoleon's bedroom at the Tuileries did nothing to alter its return to the museum.

    The Romantics turn it into a myth

    Louvre Museum, rue de Rivoli, Paris, France

    In the mid-19th century, the Mona Lisa ceased to be just one painting among many and became a literary myth.

    • 1859: Théophile Gautier described her as a "sphinx of beauty" with a mysterious smile
    • 1869: Walter Pater turned her into an almost immemorial figure, older than the rocks among which she sits

    Respect was earned. The general public was still to follow.

    The Theft of the Mona Lisa: The Empty Wall of the Salon Carré

    Salon Carré, Louvre Museum, rue de Rivoli, Paris, France

    On August 22, 1911, the painter Louis Béroud arrived at the Salon Carré to copy the Mona Lisa and found only the wall. The rooms were evacuated, the doors closed.

    • The thief, Vincenzo Peruggia, was a former employee of the museum
    • About sixty police officers and the criminologist Alphonse Bertillon found nothing
    • The scandal targeted the Louvre's negligence and made headlines around the world

    The painting, previously known mainly to art enthusiasts, became the most famous work in the world.

    The Investigation Goes Astray: Apollinaire Imprisoned, Picasso Questioned

    La Santé Prison, 42 rue de la Santé, Paris, France

    The police follow a secondary lead: Iberian statuettes stolen from the Louvre by Géry Pieret, Apollinaire's former secretary.

    Guillaume Apollinaire is arrested on September 7, 1911, and spends about a week at La Santé prison. Picasso, who had purchased one of the statuettes, is interrogated. Both are eventually cleared of the Mona Lisa case.

    When everyone is a suspect, it means the artwork has become larger than the museum itself.

    7December 1913 - January 1914Milestone

    Found in Florence, Back at the Louvre

    Uffizi Gallery, Piazzale degli Uffizi 6, Florence, Italy

    Two years after the theft, Peruggia offers the painting to the antique dealer Alfredo Geri in Florence. Geri alerts the director of the Uffizi, Giovanni Poggi, who confirms that it is indeed the original.

    The thief is arrested, the painting is exhibited in Italy, and then returns to the Louvre on January 4, 1914, twenty-eight months after its disappearance.

    Its absence has transformed it: it returns as an icon.

    8March 1920Turning Point

    Duchamp draws a mustache on her: L.H.O.O.Q.

    Avenue Charles-Floquet, Paris 7e, Paris, France

    In the autumn of 1919, Marcel Duchamp, then staying at Picabia's home in Paris, draws a mustache and a goatee on a postcard of the Mona Lisa.

    He titles it L.H.O.O.Q., the French pronunciation of which is intentionally ribald. The image appears in March 1920 in the 12th issue of the magazine 391.

    The world's most famous painting becomes a material: it can be subverted, therefore it is alive.

    The gesture would set a precedent: Dalí would follow suit in a self-portrait as the Mona Lisa, a few decades later.

    The Valfierno Legend: Six Copies and a Fake Plot

    Curtis Publishing Company Building, Sixth and Walnut Streets, Philadelphia, United States

    In the Saturday Evening Post of June 25, 1932, Karl Decker tells the story allegedly shared with him by a certain Eduardo de Valfierno: the 1911 theft was merely a means to sell six copies to buyers convinced they possessed the original.

    The story is compelling, but nothing corroborates it: no copies have ever been found, details are inaccurate, and Valfierno's very existence is not established.

    Proof that fame also attracts fables.

    1939 Evacuation: The First Safeguarding

    Louvre Museum, rue de Rivoli, Paris, France

    On the eve of the war, the painting left the Louvre on August 28, 1939. It was successively hidden in Amboise, at the Loc-Dieu Abbey, at the Château de Chambord, and then at the Ingres Museum in Montauban.

    The Mona Lisa thus escaped Nazi looting. It was the first time it was hidden to protect it from its own value.

    Nat King Cole sings "Mona Lisa"

    Capitol Studios, 5515 Melrose Avenue, Hollywood, United States

    The song "Mona Lisa", from the film Captain Carey, U.S.A. (1949), was recorded by Nat King Cole on March 11, 1950, and released on June 12, 1950.

    It remained five weeks at number one on the Billboard chart and the song won the Oscar.

    The painting was no longer just seen: it was sung all over the world.

    The 1956 Stone: Bulletproof Glass Becomes Essential

    Louvre Museum, rue de Rivoli, Paris, France

    On December 30, 1956, Ugo Ungaza Villegas, a Bolivian man, threw a stone at the painting. The glass shattered and a pigment chip broke off near the left elbow. The painting was subsequently restored.

    Since then, bulletproof glass has protected the work. This was the first moment when fame came at a physical cost.

    Washington 1963: The American Tour Begins

    National Gallery of Art, Constitution Avenue NW, Washington, United States

    In late December 1962, the Mona Lisa left France aboard the ocean liner SS France. It was exhibited at the National Gallery of Art from January 9 to February 3, 1963, in the center of the West Sculpture Hall, on a panel draped in red velvet.

    • 518,525 visitors in less than a month
    • Insurance value estimated at $100 million, a Guinness World Record
    • No insurance policy taken out: the sum was invested in security

    For the first time, a painting had a price that could not be paid.

    New York 1963: over a million visitors in one month

    The Metropolitan Museum of Art, 1000 Fifth Avenue, New York, United States

    On February 7, 1963, the Mona Lisa was presented to the public at The Metropolitan Museum of Art. Over one million visitors came to see it in a single month, according to the museum.

    It was the height of fame: people came to see an event rather than just a painting.

    Warhol Multiplies It: Thirty Are Better than One

    The Metropolitan Museum of Art, 1000 Fifth Avenue, New York, United States

    Using images from the Metropolitan Museum brochure, Andy Warhol silkscreened the Mona Lisa in a grid of thirty: Thirty Are Better than One.

    The repetition transforms it almost into wallpaper. Following Duchamp, Warhol treats it as a mass-market product.

    Tokyo 1974: Red Paint on the Showcase

    Tokyo National Museum, 13-9 Uenokōen, Taitō, Tokyo, Japan

    The Mona Lisa is exhibited at the Tokyo National Museum from April 20 to June 10, 1974, before traveling to Moscow.

    In the early days (April 20 or 21, depending on sources), a young disabled woman sprays red paint on the glass to protest the museum's lack of accessibility.

    Its fame has turned it into a platform: it is attacked to draw attention to other causes.

    The Salle des États: A Climate-Controlled Vault

    Salle des États, Louvre Museum, rue de Rivoli, Paris, France

    After maintenance work and analysis, the Mona Lisa was transferred on April 6, 2005, to the Salle des États, in a custom-made, climate-controlled enclosure behind bulletproof glass.

    • Approximately 10.2 million people see it every year (2019 data)
    • After the queue, about 30 seconds remain to stand before the painting

    Safe and sound, but further and further away.

    The Era of Attacks: Cup, Cake, Soup

    Salle des États, Louvre Museum, rue de Rivoli, Paris, France

    Behind its glass, the Mona Lisa becomes the ideal target for protest.

    • August 2, 2009: a Russian woman throws a ceramic cup at the display case
    • May 29, 2022: a man disguised as an elderly lady in a wheelchair smears a cake, in the name of the climate
    • January 28, 2024: two activists from Riposte Alimentaire throw pumpkin soup, the room is evacuated

    The painting is never touched. It has become a medium for messages, protected by what conceals it.

    A room of her own: from the announcement to the choice of architects

    Salle des États, Louvre Museum, rue de Rivoli, Paris, France

    In front of the painting, on January 28, 2025, Emmanuel Macron launched the Louvre's Nouvelle Renaissance project.

    • A new entrance, on the side of the Perrault Colonnade
    • A dedicated room for the Mona Lisa, with independent access and a specific ticket
    • New galleries under the Cour Carrée, for works announced to last until 2031

    In May 2026, a jury selected the firms Studios Architecture and Selldorf Architects. The project plans for a dedicated path for the Mona Lisa, with no opening schedule announced to date.

    Respect, glory, then showcase: the next step would be a journey where she would be alone with her visitors.
