The Most Beautiful UNESCO World Heritage Sites in Tuscany
8 places · updated 14 October 2026
In short: By our ranking, the most beautiful UNESCO World Heritage Sites in Tuscany are Boboli Gardens, Piazza del Duomo, Pisa and Siena Cathedral. The list covers 8 UNESCO World Heritage Sites. Last updated 14 October 2026.
Tuscany owes its heritage to rivalry. In the Middle Ages Florence, Siena and Pisa were independent republics competing in trade, banking and prestige, and each put its wealth into cathedrals, town halls and public squares. In the fifteenth century Florence went further and became the cradle of the Renaissance, while the countryside around Siena was shaped into the cultivated hills of the Val d'Orcia. Coloured marbles from the region's own quarries give its buildings their striped and polished look.
Pisa's Piazza del Duomo gathers cathedral, baptistery, cemetery and the Leaning Tower on a single lawn of white marble; the tower began to tilt while it was still being built in the twelfth century. In Florence, Brunelleschi's dome over the cathedral, finished in 1436, is still the largest brick dome ever built, and the Ponte Vecchio, rebuilt in 1345, carries goldsmiths' shops across the Arno.
Siena answers with its own pair. The Piazza del Campo slopes in the shape of a shell towards the Palazzo Pubblico and hosts the Palio twice each summer. Siena Cathedral is banded in black and white marble, and its floor is covered with inlaid scenes made over two centuries. Behind the Pitti Palace, the Boboli Gardens show how the Medici turned a hillside into a model for the formal Italian garden, with grottoes, statues and long cypress avenues.

01 Boboli Gardens
Giardino di Boboli
Italy · 1.6 km from Florence43.765° N 11.250° E
- UNESCO World Heritage
Image by psychographism from Pixabay Florence is the city of the Medici, and the Boboli Gardens are where that family turned a hillside into a statement of power. Rising behind the Pitti Palace, the main residence of the grand dukes of Tuscany, the garden was begun in the mid-16th century for Eleonora di Toledo, wife of Cosimo I de' Medici.
Did you know? Despite their lavishness, the gardens were reserved for the Medici family, and no parties are known to have been held in them.
02 Piazza del Duomo, Pisa
Piazza dei Miracoli
Italy · 0.5 km from Pisa43.723° N 10.395° E
- UNESCO World Heritage
Image by Pauline_17 from Pixabay Pisa's cathedral square is less a square than a lawn: a walled field on which four white marble buildings stand apart from one another like pieces set on a green cloth. The writer Gabriele D'Annunzio called it the meadow of miracles in a 1910 novel, and the name Piazza dei Miracoli has stuck.
Did you know? Construction of the leaning tower stretched over about 177 years, with the seventh floor added in 1319 and the bells only in 1372.
03 Siena Cathedral
Duomo di Siena
Italy · 1.7 km from Siena43.318° N 11.329° E
- UNESCO World Heritage
Image by Anajim from Pixabay Siena's cathedral is the product of a city that wanted to outdo Florence and very nearly did. Built between about 1215 and 1263, it is clad inside and out in bands of white and dark green-black marble, the colours of Siena's black and white coat of arms, with red marble added on the facade.
Did you know? A frieze of 172 papal busts from the 15th and 16th centuries runs around the nave and presbytery, from St Peter to Lucius III.
04 Piazza del Campo
Italy · 1.5 km from Siena43.318° N 11.331° E
- UNESCO World Heritage
Image by Zotx from Pixabay Piazza del Campo is a great tilted shell of red brick at the heart of Siena. Its fan of paving, divided by pale stone strips into nine segments, slopes down towards the Palazzo Pubblico, the Gothic town hall, whose slender brick tower, the Torre del Mangia, rises above the whole city.
Did you know? In the Palio a horse that has thrown its jockey can still win, because the victory belongs to the contrada rather than the rider.
05 Ponte Vecchio
Italy · 1.4 km from Florence43.768° N 11.253° E
- UNESCO World Heritage
Image by twalmedia from Pixabay The bridge standing today isn't the original, or even the second. A Roman-era crossing at this narrowest point of the Arno was destroyed and rebuilt more than once, wiped out again by a flood in 1117, rebuilt, then destroyed once more in the catastrophic flood of 1333.
Did you know? A bridge at this spot is first mentioned in documents as early as 996.
06 Leaning Tower of Pisa
Torre di Pisa
Italy · 0.4 km from Pisa43.723° N 10.397° E
- UNESCO World Heritage
Image by MaxiDesigns from Pixabay The tower started leaning almost as soon as it was built, and everyone building it noticed. Construction began in 1173, traditionally credited to Bonanno Pisano though historians still argue over the attribution, and by the time masons reached the third of eight planned stories, the soft ground beneath — a mix of clay, sand, and shell fragments — had already begun settling unevenly.
Did you know? The tower holds seven bells tuned to a musical scale; the oldest, La Pasquereccia of 1262, once rang to announce executions.
07 Pisa Cathedral
Duomo di Pisa
Italy · 0.5 km from Pisa43.723° N 10.396° E
- UNESCO World Heritage
Image by Makalu from Pixabay On Pisa's Piazza dei Miracoli the Leaning Tower draws the crowds, but the cathedral was there first and it is the reason the tower exists at all: the campanile is simply its bell tower. Work began in 1064 under the architect Buscheto, paid for with plunder from a Pisan raid on Muslim-held Palermo, at a moment when Pisa was racing Venice to build the most splendid church of any maritime republic.
08 Florence Cathedral
Cattedrale di Santa Maria del Fiore
Italy · 1 km from Florence43.773° N 11.257° E
- UNESCO World Heritage
Image by spalla67 from Pixabay Santa Maria del Fiore took 140 years to build, and its defining feature was an engineering problem nobody could solve when construction began. Florence approved Arnolfo di Cambio's design in 1294 and laid the first stone on 9 September 1296; the nave was finished by 1380, but the octagonal crossing, 44 metres wide and starting 52 metres above the floor, stood open to the sky for decades.
Did you know? In 1475 the astronomer Paolo Toscanelli pierced a small hole high in the dome, turning the cathedral into a giant sundial that projects the sun onto the floor.
How this list is ranked
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
Questions people ask

- Why does the Leaning Tower of Pisa lean?
- It stands on soft, unstable ground of clay and sand, and it began to sink on one side soon after construction started in 1173. Engineering work between 1990 and 2001 reduced the tilt and stabilised the tower.
- Who designed the dome of Florence Cathedral?
- Filippo Brunelleschi designed it and oversaw its construction from 1420 to 1436. He built it without a wooden supporting frame, using a double shell and herringbone brickwork.
- What is the Palio of Siena?
- It is a bareback horse race run around the Piazza del Campo every 2 July and 16 August, contested by riders representing the city's historic districts, the contrade.
