What's Inside Michelangelo’s Secret Room?

While searching for a way to add an emergency exit to Florence’s Medici Chapels in 1975, museum director Paolo Dal Poggetto stumbled upon a hidden mystery. Custodians had told him of a trapdoor concealed beneath a piece of furniture, which opened into a narrow 10-by-33-foot corridor. The room proved to be a dead end for an exit, yet Poggetto discovered something else extraordinary: Two layers of plaster had concealed long-lost charcoal and chalk sketches.

“The space is highly evocative,” says Andreina Contessa, the director general of the Bargello Museums, which include the Medici Chapels. “Its narrow, bare appearance contrasts with the monumental scale of the drawings.”

Poggetto and other scholars believe the sketches were made by artist Michelangelo during a frightful and tumultuous period of his life, when he had a falling out with the Medici family—the powerful dynasty that ruled Florence during the Italian Renaissance. Historians posit the artist hid in this dingy room while evading a death sentence in 1530.

During his lifetime, Michelangelo had a fraught relationship with the Medici family. At age 14, a young Michelangelo caught the attention of Lorenzo di Medici, the de facto ruler of Florence, who brought the talented boy under his tutelage and raised him among his own children. “He grew up alongside Giovanni and Giulio de Medici, the future Popes Leo X and Clement VII,” Contessa says.

Over the decades, the Medici, including the popes he had been raised with, commissioned many important works from Michelangelo, including artwork for the Medici Chapels in 1520. Although the family was the artist’s greatest patrons, Michelangelo didn’t always see eye-to-eye with their politics. He privately aligned himself with the Florentine Republic, which eschewed the theocratic rule of the Medici and vied for a more democratic government.

A popular Republican uprising overthrew the Medici family in 1527, and Michelangelo was reluctantly tasked with fortifying the city. “Studies have shown that Michelangelo actually tried to avoid overt political exposure,” Contessa says. “His choices were marked by great caution, shaped by professional necessity and the difficult circumstances of a particularly unstable historical period.”

However, in 1529, backed by Charles V of the Holy Roman Empire, the Medici besieged Florence and once again restored their reign. Pope Clement VII was furious with Michelangelo’s betrayal and issued the death penalty. Tensions eventually cooled, and Michelangelo was pardoned on the condition that he continue his artistic commissions. However, for about a two-month period, many historians believe Michelangelo holed up in the secret room beneath the chapel.

The room contains a well and two small hatched windows. The windows offer a glimpse of the small alleyway outside. Here, Contessa says the walls are like a sketchbook, where Michelangelo might have explored ideas and conceptualized commissions.

Dozens of human figures adorn the walls, including two flying nude male figures that resemble suspended souls in the Sistine Chapel’s “The Last Judgment.” Other drawings resemble marble statues found in the chapel just above the secret room, and some scholars argue a disembodied hand reflects the statue of David. Art historians still debate whether some or all of the drawings were done by the great artist.

Michelangelo never finished his commissioned work on the Medici Chapels and left Florence for Rome in 1534. After his death in 1564, the drawings in the secret hiding room were largely forgotten. The sketches were plastered over, and the room was used for coal storage until 1955.

After its rediscovery and an extensive restoration, the room was opened to a limited number of visitors in 2023. “I believe that visitors are primarily drawn to the room by the curiosity to discover an aspect of Michelangelo’s genius that was not intended to be seen and remained hidden for a long time,” Contessa says. She hopes that visitors will step through time and feel the sense of awe that 16th-century artists would have felt when admiring the unfiltered works of a grand master.
