Basilica of San Lorenzo in Florence: what to see inside and outside
The Basilica of San Lorenzo is easy to miss on the way to the Duomo. Its facade is gray and deliberately unfinished, with no marble cladding. Yet inside you will find much of the Medici family's legacy.
Entry to the basilica complex is paid (as of 09/2026, complex page). The adjacent Medici Chapels with the tombs by Michelangelo are sold separately, and you usually buy these two tickets together.
Below we break down what to see in the complex, how the Old Sacristy differs from the New Sacristy, and how to get in without a long line.

The essentials on the Basilica of San Lorenzo

San Lorenzo consists of several parts, not a single museum. The complex includes the church itself, Brunelleschi's Old Sacristy, the cloisters, the Museo del Tesoro, the crypt, and the underground areas. The New Sacristy and the Chapel of the Princes, meaning the Medici Chapels, belong to the Bargello Museums and require a separate ticket (Medici Chapels tickets), which you buy right at the entrance.
History: from an early Christian church to the Medici
The first church on this site appeared in the late 4th century AD. It was commissioned by Ambrose, the Archbishop of Milan. More than fifteen hundred years have passed since then, and today it is one of the oldest churches in Florence.
It housed the relics of two saints. Lawrence was a Roman deacon who died during the persecutions of Emperor Valerian. Zenobius became the first bishop of Florence, and according to tradition he had the gift of healing. It was the relics of Lawrence that gave the church its second name.
The full Italian name is Basilica di San Lorenzo. Literally, that is the Basilica of Saint Lawrence. In guidebooks you will see both the full name and the short form "San Lorenzo."
Until the early 7th century, San Lorenzo was the city's main cathedral. Later that status passed to Santa Maria del Fiore, the future Duomo. The original building stood almost until the 11th century.

Money for the work was raised by the whole city, which is why the basilica of that period is called the people's church. The simple early structure gave way to a more austere appearance with blank walls.
The next chapter of the story is tied to Giovanni di Bicci, the head of the Medici family. He planned to establish a family burial place here and commissioned Filippo Brunelleschi to carry out the rebuilding. It was Brunelleschi who designed the plan for the future building and its interior layout.
In 1421 a large-scale construction project began on the site (complex portal). For seven years Brunelleschi built the Old Sacristy, and the word "sacristy" itself comes from Italian and means a room for sacred vessels and objects.
A sacristy is used as a vestry near the altar. It stores clergy vestments, books, prayer books, and vessels for services. The priest comes out from here to the congregation and returns here after Mass.
The Old Sacristy also became the site of the first Medici burial. The plan was for Brunelleschi to continue rebuilding the entire church after that. It did not happen: Giovanni di Bicci died and was buried in the new burial place, and the money for construction ran out.
Work resumed only in 1441, under Cosimo de' Medici, Giovanni's son. The architect was Michelozzo di Bartolomeo, and construction lasted about twenty years, until 1461 (complex archive).
A few years later, Cosimo de' Medici died and was also buried in the basilica's crypt. From then on, all members of the family were buried here. This is how San Lorenzo became the Medici family mausoleum.
About sixty years passed, and Pope Leo X, also a Medici, decided to expand the church and commissioned Michelangelo Buonarroti for the work. In 1520, he began the New Sacristy, where subsequent Medici family members were to be buried.
Michelangelo arranged the space differently from the accepted norm and placed the tombs along the walls rather than in the center of the hall. He also designed the tombstones and built a small chapel inside.
The master was also supposed to redesign the basilica's main facade. Michelangelo wanted to clad it in Carrara marble, while the Medici insisted on Pietrasanta marble. The dispute came to nothing, and the architect abandoned the project.
That is why the facade of San Lorenzo remained plain, without cladding. In the 15th century, bronze pulpits by Donatello were added to the basilica, and the last major addition was the Chapel of the Princes, built in the 17th century to a design by Matteo Nigetti.
Today, San Lorenzo operates as an active Catholic church and museum complex. Masses are held here, and tourists view several exhibitions at once, so lines can be long and you are better off arriving at opening time.
Architecture: a stark facade without cladding
In the 15th century, the facades of Florence's churches were decorated with marble, reliefs, and statues. Against that backdrop, San Lorenzo looks deliberately austere. Blank ivory-colored stone walls, straight lines, orange domes, and small arched windows.

The cladding was never completed, so the building stands as Brunelleschi originally envisioned it, and the bare facade reminds you of Michelangelo's dispute with the Medici over marble.
Interior: three naves and marble
© Zairon · CC BYPhoto: Zairon, CC BY (https://creativecommons.org/licenses/by/4.0), Wikimedia CommonsInside, the basilica has three naves separated by columns installed by the architect Vasalletto. Geometric patterns are visible on the floor and ceiling, and marble, gilding, and rich decoration are everywhere.
The central hall is especially beautiful in sunlight, when light streams through the arched windows. Every room here deserves individual attention, so take your time: you still have the chapels and the library ahead of you.
What to see inside
Most of the interior decoration is concentrated in a few rooms. In the basilica you visit the Old Sacristy, the cloister, and the Laurentian Library. The New Sacristy and the Chapel of the Princes belong to the Medici Chapels, which have a separate entrance.
Old Sacristy
© Ricardalovesmonuments · CC BY-SAPhoto: Ricardalovesmonuments, CC BY-SA (https://creativecommons.org/licenses/by-sa/4.0), Wikimedia CommonsThe Old Sacristy was built by Brunelleschi, and the interior decoration was created by Donatello. He made the bas-reliefs on biblical subjects and the colored medallions under the arched lunettes. He worked here in 1442.
- What to look for: the depiction of the starry sky on the inside of the dome.
- Who is buried here: Giovanni di Bicci with Piccarda, as well as Piero and Giovanni de' Medici; their tomb was created by Verrocchio.
- Important: the room is included in the complex ticket, no extra payment needed.
New Sacristy
The New Sacristy was designed by Michelangelo himself, and it took about fifteen years. People come here from all over the world to see his sculptures. This is one of the master's best works of his entire life.
- What to look for: the allegories of Day, Night, Dawn, and Dusk, as well as the Madonna and Child above Giuliano's tomb.
- Who is buried here: Lorenzo and Giuliano de' Medici.
- The catch: this is already the Medici Chapels with a separate ticket, not part of the basilica complex.
Chapel of the Princes

The walls here are clad in expensive marble, with Medici coats of arms set into it. The dome was frescoed by Pietro Benvenuti.
- What to look for: the marble cladding with coats of arms and two statues, Cosimo de' Medici and Ferdinand I.
- Important: the further decoration was never completed, so there are fewer statues here than planned.
- Who is buried here: the remaining members of the Medici family.
Laurentian Library

This is one of his most famous architectural works. It houses a large collection of ancient books and manuscripts, some of them extremely rare.
- What to see: the unusual staircase, whose steps seem to flow downward, and the manuscript hall.
- Important: the library operates as a working library, the reading room is open only by appointment, maximum 10 people per day (library schedule).
- The catch: getting inside is harder than getting into the basilica itself.
Cloister

- How to find it: the exit to the cloister is on the side of the Laurentian Library.
- The catch: without a separate exhibition, it is just a passageway, you won't spend much time here.
Tickets and opening hours
Tickets for San Lorenzo are not straightforward: there is no single ticket for the whole complex. Each site is paid for separately, and that's worth planning for in advance.

Stanza segreta di Michelangelo | 32 €, by appointment only (as of 09/2026) | charcoal drawings on the walls beneath the New Sacristy (tickets with a guided tour) |
Laurentian Library | by prior appointment only | reading room with rare manuscripts (appointment rules) |
The complex is open Monday through Saturday, from 10:00 to 17:30, with the last entry at 16:30. Closed on January 1, January 6 and August 10; otherwise the schedule is stable. We checked the hours on 14.09.2026 on the visitor page.
You can buy a complex ticket directly at the ticket office by the entrance; there is no need to book it in advance. Online booking makes sense for guided tours.

The basilica is an active church, and masses are held here on Sundays. Entry to the church for worship is free, and you do not need a ticket. Children under 12 and visitors with disabilities enter free of charge (visiting rules).

Where it is and how to get there
Address: Piazza di San Lorenzo, 9. The basilica stands in the historic center, on the square that bears its name. The San Lorenzo market operates nearby, so you are unlikely to walk past it.
From the Duomo to San Lorenzo is about 400 m, a 5-minute walk (on the map). From Santa Maria Novella station it is roughly 850 m, or a 10-12 minute walk (on the map). Taking transport from the center makes little sense; it is faster to walk.
