Medici Chapels

The Medici Chapels are a state museum in Florence, Italy, comprising two chapels built between the 16th and 17th centuries as an extension to the Basilica of San Lorenzo. Located on the Piazza Madonna degli Aldobrandini, the complex consists of the Sagrestia Nuova, or New Sacristy, designed by Michelangelo, and the larger Cappella dei Principi, or Chapel of the Princes, a collaboration between the Medici family and architects. The chapels were created to celebrate the Medici family, patrons of the church and Grand Dukes of Tuscany, and serve as their primary mausoleum. Declared a national monument and transformed into a state museum in 1869, the Medici Chapels are now managed as part of the Bargello Museums group and rank among Florence's most visited cultural sites, attracting 317,135 visitors in 2014.

The decision to establish a family mausoleum at San Lorenzo dates to the 14th century, with Giovanni di Bicci de' Medici and his wife Piccarda buried in Brunelleschi's Old Sacristy. The project for a proper dynastic mausoleum was conceived in 1520 when Cardinal Giulio de' Medici, the future Pope Clement VII, commissioned Michelangelo to build the New Sacristy for members of his family. Michelangelo worked on the architecture from 1519 to 1524 and on the sculptures until 1534, though the project was disrupted by the temporary exile of the Medici in 1527, the death of Clement VII, and Michelangelo's permanent departure for Rome. Giorgio Vasari and Bartolomeo Ammannati completed the work by 1555 under Cosimo I. The Cappella dei Principi was conceived by Cosimo I but realized by his successor Ferdinando I, who began construction in 1604 following designs by Don Giovanni de' Medici, with Matteo Nigetti as architect and Bernardo Buontalenti modifying the plans. The chapel's elaborate marble revetment, executed by the Opificio delle Pietre Dure established for this purpose, took centuries to complete. The dome was frescoed by Pietro Benvenuti between 1828 and 1837 under the Habsburg-Lorraine dynasty. In 1976, a concealed corridor with charcoal drawings attributed to Michelangelo was discovered beneath the New Sacristy. Since 2014, the museum has been managed by the independent museum group of the Museo del Bargello.

The museum's holdings center on two distinct but complementary expressions of Medici power and artistic patronage. The Sagrestia Nuova represents the pinnacle of Michelangelo's sculptural and architectural integration, containing monumental tombs with allegorical figures that influenced generations of sculptors. The Cappella dei Principi exemplifies Baroque court art through its spectacular revetment of inlaid marbles and semi-precious stones, a technique known as commesso fiorentino. The collection also encompasses the crypts below, which contain the actual remains of the Grand Ducal family, and the Lorenese Crypt for the Habsburg-Lorraine successors. The museum's scope extends to include a significant collection of 16th- and 17th-century reliquaries and devotional objects produced by goldsmiths active at the Florentine court, displayed as part of the exhibition path 'Nel segno dei Medici. Tesori sacri della devozione granducale.' The institution also preserves the archaeological and anthropological record of the Medici dynasty, with scientific examinations conducted since 2004 clarifying aspects of the family's physical history and disproving some 19th-century claims.

The Sagrestia Nuova contains Michelangelo's tombs for Giuliano di Lorenzo, Duke of Nemours, and Lorenzo di Piero, Duke of Urbino, each featuring idealized seated figures flanked by allegorical sculptures. Giuliano's tomb is accompanied by Night and Day, while Lorenzo's features Dawn and Dusk, personifications of the four times of day that became enormously influential for subsequent reclining figures on architraves. The Madonna and Child, completed first for the project, sits above the simpler sarcophagus containing Lorenzo the Magnificent and his brother Giuliano, flanked by Saints Cosmas and Damian executed by Montorsoli and Baccio da Montelupo after Michelangelo's models. In the Cappella dei Principi, six grand sarcophagi stand empty, as the Medici remains are interred in the crypt below; the niches intended for portrait sculptures hold only two completed works, bronze statues of Ferdinando I and Cosimo II by Pietro Tacca. The chapel's dado contains sixteen compartments with coats of arms of Tuscan cities under Medici control, rendered in mother-of-pearl, lapis lazuli, and coral. The 1978 discovery of Michelangelo's Secret Room revealed approximately 180 charcoal sketches on its walls, with 97 identifiable as by Michelangelo's hand based on their correspondence to his known works.

The Sagrestia Nuova, entered originally through a discreet corner of San Lorenzo's right transept, consciously competes with Brunelleschi's Sagrestia Vecchia in its format of a cubical space surmounted by a dome, using gray pietra serena and whitewashed walls. Michelangelo's architecture is notable for its proto-Mannerist tension and inversion of classical rules, with a many-layered articulation of the wall plane. The Cappella dei Principi is an octagonal structure 28 meters wide, surmounted by a dome 59 meters high, the second most majestic in Florence after Brunelleschi's Duomo dome. Positioned on the same axis as the nave and chancel, it functions as an apsidal chapel and is accessed from the exterior through a low vaulted crypt planned by Buontalenti. The chapel's astonishing revetment entirely covers the walls with jig-sawn fragments of specimen stones and porphyry, an expression of court art that employed the specialized techniques of the Opificio delle Pietre Dure. The crypt beneath features an octagonal floor with ribbed vaults, and a second crypt behind the altar houses the remains of the last Grand Duke, Gian Gastone de' Medici.

The Medici Chapels are located at Piazza di Madonna degli Aldobrandini 6, accessible from the rear of the Basilica of San Lorenzo. The museum operates under the Bargello Museums group, with full-price admission at 11 euros and a 72-hour cumulative pass for all Bargello Museums at 38 euros. Free admission is offered on the first Sunday of each month and on April 25, June 2, and November 4. The museum is equipped with disabled access facilities, including ramps on the ground floor, an elevator to the Cappella dei Principi, and a platform lift to the Sagrestia Nuova. Visits to Michelangelo's Secret Room require advance reservation, last 15 minutes, and are limited to four people per slot; access involves a narrow staircase of 12 steps and is not available to children under 10, unaccompanied minors, or individuals with mobility limitations, heart conditions, or claustrophobia. Audioguides are available in Italian and English. The museum occasionally hosts temporary exhibitions, such as the 2012 exhibition on Pope Leo X and the 2014 exhibition marking 400 years since the death of Ferdinando I de' Medici.
