Florence: The Renaissance Circuit

Then a goldsmith named Filippo Brunelleschi stepped forward. He said he could build it without any scaffolding rising from the floor, without any wooden framework to hold the masonry in place during construction. The committee had him physically removed from the meeting. He kept coming back. Eventually they ran out of other ideas and gave him the job.

Between fourteen twenty and fourteen thirty-six, Brunelleschi pulled off one of the great engineering feats in human history. His solution was a double shell — two nested domes, connected by twenty-four stone ribs — and a herringbone brick pattern that locked each new layer of masonry into the courses below, so the whole structure became self-supporting as it rose. He invented new hoisting machines, including an ox-driven hoist that could reverse direction without unhitching the animals, to lift over four million bricks up to the workers. The finished dome weighs roughly twenty-five thousand tonnes and the top of the lantern sits a hundred and sixteen metres above the piazza floor.

It remains to this day the largest masonry dome ever constructed. Not the largest when it was built. The largest ever built. In nearly six hundred years, nobody has surpassed it.

Now step back and look at the full composition. To the left of the cathedral entrance stands Giotto's Bell Tower — the Campanile — an almost eighty-five-metre shaft of pink, white, and green marble, begun by the painter Giotto di Bondone in thirteen thirty-four and completed by Francesco Talenti in thirteen fifty-nine. Giotto died in thirteen thirty-seven having finished only the lowest section, but his design set the chromatic palette — Carrara white, Prato green, and Siena pink — that defines the visual identity of the whole Duomo complex.

If you want to climb inside the dome, the entrance is on the north side. The ascent runs between the two shells, up four hundred and sixty-three steps, past Giorgio Vasari's enormous Last Judgment fresco covering the interior, painted between fifteen seventy-two and fifteen seventy-nine. At the top, the view of Florence in every direction is the best in the city.

For now, turn to your left. The octagonal building clad in white and green marble directly in front of the cathedral is your next stop.

Every Florentine was baptised here for centuries. That includes Dante Alighieri, born in twelve sixty-five and baptised in this very font. Scholars believe the terrifying Byzantine mosaic of the Last Judgment inside — Christ enthroned, the damned descending into monstrous jaws — influenced his vision of Hell in the Divine Comedy. If you step inside, look up: that ceiling mosaic was created in the thirteenth century, and the central Christ figure measures roughly eight metres tall.

But now look at the east doors — the gilded bronze panels facing the cathedral. These are the Gates of Paradise. In fourteen oh one, the Arte di Calimala — the wool merchants' guild — announced a competition for new bronze doors. Seven sculptors entered; each had to produce a panel depicting the sacrifice of Isaac. The two finalists were Lorenzo Ghiberti, a goldsmith of twenty-three, and Filippo Brunelleschi, a goldsmith of twenty-four.

Both submission panels survive in the Bargello Museum. Ghiberti's is lighter, more graceful, more classically composed. He won — narrowly. Brunelleschi was reportedly so devastated that he abandoned sculpture and threw himself into studying Roman architecture. Which is how he ended up designing, twenty years later, the dome you were just standing beneath. One competition produced two of the greatest figures of the entire Renaissance.

Ghiberti spent twenty-one years on the north doors, then immediately began his masterpiece: the east doors, worked on from fourteen twenty-five to fourteen fifty-two. Ten gilded panels depicting scenes from the Old Testament — the Creation, Cain and Abel, Noah, Abraham, Joseph, Moses — each one a revolution in pictorial depth and spatial perspective. Ghiberti solved, in bronze, the same problem painters were wrestling with in fresco: how to suggest three-dimensional space on a flat surface. When Michelangelo saw the completed doors, he reportedly declared them worthy of being the Gates of Paradise. The name has stuck for over five hundred years.

What you see today are copies — high-quality replicas installed in nineteen ninety when the originals were moved to the Museo dell'Opera del Duomo around the corner for protection. But even these reproductions, in the morning light, give you a sense of what Ghiberti achieved: a door that tells the entire Old Testament in ten panels, with a depth and humanity that feels startlingly modern.

From the Baptistery, walk south-west down Via Roma, past the loggia-lined street, and in about two minutes you'll emerge into the square that sits on top of ancient Florence itself.

Two thousand years ago, this exact location was the Roman Forum of Florentia — the city Julius Caesar's veterans founded around fifty-nine BC. The two main Roman roads of the city crossed right here: the cardo maximus running roughly north-south, and the decumanus maximus running east-west. At their intersection stood the forum, with its temples, markets, and colonnaded public spaces. The Column of Abundance — the Colonna dell'Abbondanza — that you can see standing in the square marks that original Roman crossroads. The present column dates to fourteen thirty-one, topped with a statue of Abundance by Giovan Battista Foggini from seventeen twenty-one, which replaced a Donatello original that had eroded beyond saving. But the column's position is unchanged from antiquity.

For centuries after Rome, this area became the Mercato Vecchio — the Old Market — the trading heart of medieval Florence. The Jewish Ghetto established in fifteen seventy-one occupied much of the surrounding area. Tower houses rose between the market stalls. The alleys were narrow, crowded, and extremely medieval.

Then in the eighteen eighties, Florence's municipal government — emboldened by the city's brief service as capital of the newly unified Kingdom of Italy from eighteen sixty-five to eighteen seventy-one — decided to modernise. They demolished virtually everything. The entire medieval neighbourhood was flattened and replaced with the Haussmann-inspired piazza and arcaded streets you're standing in now. The triumphal arch on the west side of the square bears a Latin inscription that translates roughly as: the ancient city centre, freed from centuries of squalor, restored to new life. Historians note, more drily, that they erased an irreplaceable medieval neighbourhood and felt very good about it.

The cafes lining the square are genuinely historic even if the piazza itself is not. On the south side, the Caffe Giubbe Rosse — named for the red Viennese-style smoking jackets worn by the waiters when it opened in eighteen ninety-six — became the gathering place of the Italian Futurist movement from about nineteen thirteen onward. Poets and painters argued about modernity and the future in the back rooms here. The coffee is still good. Sitting down at any of the square's pavement cafes comes with a tourist surcharge that will make you wince, but a quick espresso at the bar is entirely reasonable.

From here, walk south on Via Calimala toward the river. The street is one of Florence's oldest trading routes, and it will take you, in about five minutes, to the edge of one of the most celebrated art collections ever assembled.

The transformation into an art museum happened gradually. Cosimo's son Francesco the First de' Medici, more interested in art and alchemy than in politics, converted the top floor into a gallery space in fifteen eighty-one. This is widely considered among the first purpose-built art museums in the world open to invited visitors. The Medici spent generations filling it with masterpieces acquired by purchase, inheritance, and occasionally by methods it's better not to ask about.

The collection was secured for Florence forever by the last Medici heir, Anna Maria Luisa de' Medici, who died in seventeen forty-three. She bequeathed the entire collection to the city with a single binding condition: none of it could ever leave. This clause, known as the Patto di Famiglia, is the reason that Botticelli's Birth of Venus, Leonardo's Annunciation, and Caravaggio's Medusa are all still here rather than scattered across European royal collections.

The gallery was opened to the general public in seventeen sixty-nine. If you plan to go in, book tickets online well in advance — the queue for walk-ins stretches for hours. Inside, the arrangement is roughly chronological, from the medieval gold-leaf saints of Cimabue through Giotto's revolutionary three-dimensional space, then onward through Botticelli, Leonardo, and Michelangelo.

Even from out here, look at the niches between the columns running along both sides of the courtyard. Between eighteen forty-two and eighteen fifty-six, twenty-eight marble statues of celebrated Tuscans were installed here. You can pick out Dante, Petrarch, Boccaccio, Machiavelli, Leonardo da Vinci, Michelangelo, Galileo, and Amerigo Vespucci — the Florentine navigator whose first name was given to two entire continents. The hall of fame of the Renaissance, assembled in stone, looking down on the people who come to admire their legacy.

Walk to the far end of the courtyard and look through to the river. That view down the Arno — the bridges in sequence, the hills of the Oltrarno rising beyond — is one of the loveliest in Florence. Then turn left and walk toward the Loggia.

The name comes from the Landsknechte — German mercenary soldiers, known in Italian as lanzichenecchi and shortened to lanzi — who were garrisoned here in the sixteenth century under Cosimo the First de' Medici.

Now look to your left. That bronze figure is Perseus, by Benvenuto Cellini, cast between fifteen forty-five and fifteen fifty-four and installed here in fifteen fifty-four. Perseus stands with his sword in his right hand and the severed head of Medusa raised aloft in his left, blood streaming in bronze rivulets from her neck. Medusa's headless body writhes beneath his feet in a kind of horrible throne. It is violent, technically astonishing, and one of the defining works of Mannerist sculpture.

The story of its casting is nearly as dramatic as the sculpture itself. Cellini, in his extraordinary autobiography, describes the night the bronze began to seize in the furnace. The metal was overheating, the mould was at risk of failing. In desperation, Cellini ordered his assistants to throw every piece of pewter in his household — about two hundred plates, dishes, and bowls — into the furnace to thin the bronze and keep it liquid enough to flow. It worked. When they opened the mould, Perseus emerged nearly perfect. Cellini collapsed immediately afterward with a high fever.

On your right stands Giambologna's Abduction of the Sabine Women, carved between fifteen seventy-nine and fifteen eighty-three from a single block of marble. Three figures — a young man, the woman he is lifting, and an older man crouching beneath — spiral upward together in a continuous helical movement. It was the first large-scale European sculpture designed to have no single front or back: every angle is equally composed, equally dramatic. Giambologna reportedly gave the work no title when it was finished. The Sabine subject was suggested afterward to provide a narrative context for what he'd actually made, which was a pure formal exercise in three-dimensional movement. That the mythology fits so well is simply good luck.

Take your time here. Walk around Giambologna's group twice. Watch how the composition changes from every viewpoint, how the three figures interlock and counterbalance in ways that seem almost impossible from a single block of stone. Then, when you're ready, step out of the loggia and look left at the enormous square stretching before you.

For the first two centuries, those shops belonged to butchers, fishmongers, and tanners — trades that found it convenient to dump their waste directly into the river through gaps in the floorboards. The Arno beneath the bridge reportedly ran pink on busy days. Efficient. Repellent. Very medieval.

Everything changed in fifteen sixty-five, when Cosimo the First de' Medici commissioned Giorgio Vasari to build an elevated private corridor connecting the Palazzo Vecchio, through the Uffizi building, over the Ponte Vecchio, and all the way to the Palazzo Pitti on the south bank. This became the Vasari Corridor — roughly seven hundred and sixty metres of enclosed raised walkway, constructed in just five months. The Medici could now move between their political headquarters and their home without ever setting foot among the public.

But the corridor ran directly over the bridge shops, and the Grand Duke Ferdinando the First — Cosimo's son — could not tolerate the smell of rotting meat rising into his private commute. So in fifteen ninety-three, he issued a decree: all butchers off the bridge. From that date forward, only goldsmiths and jewellers were permitted to trade here. That ruling has held for over four hundred years. The glittering gold shops you see today exist because a Medici grand duke had a sensitive nose.

Now, the most important story this bridge carries: on the night of the third of August, nineteen forty-four, German forces demolishing Florence's crossings as they retreated blew up every bridge across the Arno — the Ponte Santa Trinita, the Ponte alle Grazie, the Ponte alla Carraia — every one except this. The most widely accepted explanation is that Hitler, who had visited Florence in May nineteen thirty-eight, gave direct orders that the Ponte Vecchio be spared. The Germans did demolish the medieval buildings on both approaches to create rubble barriers blocking Allied vehicles — you can see the post-war rebuilding on both ends — but the bridge itself they left intact.

Walk across. Lean over the railing midway and look down at the Arno. The river slides beneath you, brown and slow in summer, swift and grey in winter. On your right as you cross, a narrow opening in the buildings above the bridge reveals the underside of the Vasari Corridor, still running its route along the rooftop. On the far side, you're in the Oltrarno — the other side of the Arno — a different Florence entirely.

Look toward the left side of the square, near the large Neptune Fountain by Bartolomeo Ammannati — the one Michelangelo supposedly called a waste of good marble. Search the paving stones nearby for a round bronze plaque embedded in the ground. Found it? That marks the spot where Girolamo Savonarola was hanged and burned on the twenty-third of May, fourteen ninety-eight.

Savonarola's story is one of the most extraordinary in Renaissance Florence. He was a Dominican friar from Ferrara who arrived in Florence in fourteen eighty-two and, through the sheer force of his preaching, became the most influential voice in the city. His sermons — some lasting four hours in the packed cathedral — were electrifying descriptions of divine punishment, corruption, and vanity. He predicted the French invasion of fourteen ninety-four with enough accuracy that when it happened, his authority became absolute. When the Medici were expelled, Savonarola essentially ran Florence as a theocratic republic.

In fourteen ninety-seven, he organised the Bonfire of the Vanities right here in this square: citizens were pressured to bring mirrors, fine dresses, cosmetics, playing cards, books of poetry, musical instruments, and paintings to be burned in an enormous pyre. Some of Botticelli's works may have been destroyed in those flames — Botticelli himself, according to some accounts, threw his own paintings in. Then Savonarola pushed too far. He attacked the Pope. He was excommunicated. The city turned on him. He was arrested, tortured in the Palazzo Vecchio, hanged from a cross-shaped gallows in this square, and his body was burned so that no relics could be collected. The ashes were thrown into the Arno.

Someone still leaves flowers on the plaque.

The square also contains — in the Loggia dei Lanzi you visited earlier, just visible on the south side — Cellini's Perseus and Giambologna's Sabine group. And just to the left of the Palazzo Vecchio entrance stands a copy of Michelangelo's David. The original stood here from fifteen oh four, when Michelangelo completed it, until eighteen seventy-three, when it was moved to the Accademia gallery for protection. For nearly four hundred years, a five-metre-tall marble David stood at this corner, looking out across the square where Florence conducted its most important business. The position was not accidental. David was the small republic's symbol of defiance against larger, more powerful enemies. He faced the road toward Rome.

The church facing you across the piazza is the Basilica di Santo Spirito, and it is one of the last buildings designed by Filippo Brunelleschi — the same man responsible for the dome you were standing under this morning. He began work on this church in fourteen thirty-four, two years before the dome was completed. He died in fourteen forty-six, with the building unfinished, and construction continued under others until the church was consecrated in fourteen eighty-one.

Brunelleschi's design was radical: a Latin cross plan with forty semicircular side chapels flowing around the entire perimeter of the interior, creating a continuous undulating wall. His intention was for this rippling surface to be visible on the exterior too, giving the building an organic, almost breathing quality from the outside. After his death, the builders opted for a flat exterior wall instead. The facade remains today as bare plaster — officially unfinished, practically speaking, for five hundred and forty years. Brunelleschi would not have approved.

Step inside if the church is open. The interior is one of the most harmonious spaces of the early Renaissance: thirty-five slender grey stone columns in perfect rhythmic sequence, every proportion calculated with mathematical precision. It is calm, ordered, luminous. In the sacristy off the left transept, you will find a wooden crucifix — slightly over life-size — carved by a seventeen-year-old Michelangelo Buonarroti. After the death of his patron Lorenzo de' Medici in fourteen ninety-two, the young Michelangelo was given shelter here by the Augustinian monks. In exchange, he was allowed access to the convent's hospital morgue, where he could study human anatomy by dissection. The crucifix he carved for the church as payment disappeared for centuries, lost under layers of later paint, and was only rediscovered in nineteen sixty-two by the German art historian Margrit Lisner, hanging forgotten in a corridor. Experts who examined it noted the anatomical accuracy of the figure — a young male body, the kind of knowledge you would gain not from observation of the living but from careful study of the dead.

For food, Piazza Santo Spirito is one of the better locations in Florence. Gusta Pizza on nearby Via Maggio does excellent thin-crust pizza at prices that will seem almost implausibly low compared to the north side of the river. Eat on the church steps. It is entirely the right thing to do.

The competition ended badly for Pitti. He had been a political ally of Cosimo de' Medici, and when Cosimo died in fourteen sixty-four, Luca's influence evaporated. He joined a conspiracy against Cosimo's son Piero de' Medici, was found out, lost his political standing, ran out of money, and died in fourteen seventy-two with the palace only partially built.

Guess who bought it. In fifteen forty-nine, Eleonora di Toledo, wife of Grand Duke Cosimo the First de' Medici, purchased the unfinished building and set about transforming it into the official ducal residence of Tuscany. The architect Bartolomeo Ammannati extended it substantially, adding the rear courtyard and the two great wings. Over the following three centuries, the Palazzo Pitti served as home to every ruling dynasty in Tuscany: the Medici, the House of Lorraine, and briefly, when Florence was the capital of unified Italy from eighteen sixty-five to eighteen seventy-one, the Italian royal family. Napoleon used it as his Florence headquarters too.

Today the palazzo houses five separate museums. The most significant is the Palatine Gallery on the second floor, which contains one of the greatest concentrations of Raphael and Titian paintings in Europe. If you have an hour, go straight to the Palatine and find Raphael's Madonna of the Chair — a circular painting of the Virgin and Child that is so intimate, so warm, so entirely free of the formal distance of most Renaissance religious painting, that it has been a source of sustained wonder for five centuries.

Behind the palace, filling the hill above, are the Boboli Gardens: forty-five hectares of formal terraces, fountains, grottos, and amphitheatre, created from fifteen forty-nine onward by Eleonora di Toledo and the Medici. They are among the most influential gardens in European history — Versailles drew directly on their example. On a warm afternoon, with a few hours to spare, they repay every minute.

From here, follow the crowds south and then east to find your final stop.

The piazzale — the name simply means large square — was designed by the architect Giuseppe Poggi in eighteen sixty-nine as part of a sweeping modernisation of Florence during its years as capital of the newly unified Italy. Poggi demolished the old city walls along the south bank of the Arno and replaced them with the tree-lined avenues you walked up. This terrace was the centrepiece: a grand public belvedere dedicated to Michelangelo, ringed with copies of his most celebrated works.

The bronze statue at the centre of the square is a copy of the David, hauled up here by nine pairs of oxen on the twenty-fifth of June, eighteen seventy-three — the same day the original was moved from Piazza della Signoria to the Accademia gallery for protection. The four figures around the base of the pedestal are copies of the allegorical sculptures of Dawn, Dusk, Day, and Night from the Medici Chapel at San Lorenzo. Poggi's original plan was for the neo-classical loggia behind you to become a museum dedicated to Michelangelo's work. The museum never materialised. A restaurant called La Loggia opened instead. Very Florentine.

The best time to be here is the hour before sunset, when the light turns amber and the dome of the cathedral seems to glow from within. The piazzale fills with locals, musicians, tourists, and vendors selling cold drinks. It is a party with the most beautiful backdrop in Europe. If you want a quiet version, walk fifty metres to the left along the railing. The view is identical and you will likely have it almost to yourself.

Look out one more time over the city. Everything you walked through today is visible from here: the dome Brunelleschi was told he couldn't build, the Baptistery that sparked the great competition that launched the Renaissance, the medieval square that witnessed both its highest achievements and its darkest moments, the bridge that survived a war because someone with power thought it too beautiful to destroy. And beyond the river, the Oltrarno hillside where the artisans and the real Florentines have always lived.

This walk covered roughly four kilometres and nearly seven centuries of one of the most concentrated explosions of human creativity the world has ever seen. Florence did not do things by halves. Neither should you.
