SIENA UP CLOSE
Siena's Piazza del Campo, Duomo & the Palio, Explained
A closer look at the shell-shaped square, the striped Gothic cathedral, and the twice-yearly bareback horse race that still runs through the heart of Siena.

The Piazza del Campo is Siena's stage, a sloping, shell- or fan-shaped square that has served as the city's civic centre since the 13th century, when Siena was governed by the Council of Nine (the Noveschi). Its brick paving is divided into nine wedge-shaped sections radiating from the low point at the Palazzo Pubblico, one for each of the ruling council members — a deliberate piece of medieval urban design rather than an accident of the terrain. Widely regarded as one of Europe's great medieval squares, it's ringed by warm brick palazzi with almost no modern intrusion, which is part of why it still feels so completely of its period.
The Torre del Mangia and Palazzo Pubblico
Rising from the Palazzo Pubblico at the piazza's low end is the Torre del Mangia, a slender brick bell tower completed in the 14th century and, for a long stretch, among the tallest secular towers in Italy. It was built to a height that reportedly matched Siena's cathedral tower, a deliberate statement that civic and religious power in the city were equals. Inside the Palazzo Pubblico, visitors can see the Sala della Pace and its famous fresco cycle on good and bad government — a rare piece of purely secular medieval art, commissioned by the same council the piazza's nine sections honour.
The Duomo's black-and-white stripes
Siena's cathedral is instantly recognisable for its bands of dark green-black and white marble, colours drawn from the Balzana, the black-and-white shield that is Siena's civic emblem. Begun in the 1200s in the Italian Gothic style, the Duomo was originally intended to be even larger — an ambitious extension, the Facciatone, was abandoned after the Black Death of 1348 crippled the city's population and finances, and its unfinished wall still stands as a viewing platform today. Inside, the inlaid marble floor, built up over roughly two centuries by numerous artists, is considered one of the most elaborate in Italy and is usually only fully uncovered for part of the year.
The Palio — Siena's horse race
Twice each summer, on 2 July and 16 August, the Piazza del Campo is transformed into a dirt racetrack for the Palio di Siena, a bareback horse race that has run in some form since at least the medieval period. Ten of the city's seventeen contrade, or historic neighbourhood districts, compete in each race — only ten can fit around the piazza's tight track, so the exact line-up rotates. The race itself lasts barely more than a minute, three laps of the square, but the pageantry, neighbourhood rivalry, and centuries of tradition around it make the Palio one of Italy's most distinctive living traditions, not a staged spectacle for tourists.
The contrade — Siena's living neighbourhoods
Long before and after race day, Siena is organised around its seventeen contrade — historic wards, each with its own animal or symbol (the Eagle, the Tortoise, the Porcupine, the She-Wolf, and others), church, museum, and fierce local identity. Residents are typically baptised into their contrada and remain loyal to it for life, and rivalries between certain contrade run centuries deep. Wandering Siena's streets, you'll spot contrada flags, painted symbols, and small chapels well outside Palio season — a reminder that the race is the visible peak of a neighbourhood culture that shapes daily life in the city year-round, distinct from anywhere else in Tuscany.
