Piazza Maggiore Bologna: complete guide to the square

At a glance

If there is one place to start from in Bologna, it is this one. Piazza Maggiore is the city’s living room: the point where the streets of the centre converge, where people arrange to meet, where locals sit on the steps of San Petronio and watch the world go by. It is not a museum square to cross quickly — it is a living, breathing place used by Bolognesi every single day.

This guide is written for visitors arriving by train who want to understand what they are looking at: the history in brief, the real dimensions, and what to look for on each side of the square. No inflated enthusiasm — just what you need to visit it calmly and know where to direct your gaze.

A square as old as the city’s self-governance

Piazza Maggiore came into being in the thirteenth century, when the free Comune of Bologna decided to give itself a public space worthy of its importance. The core of the square took shape from around 1200 onwards, and over the following centuries the buildings of civic and religious power that still surround it today took up their places.

For centuries it was the commercial, political and social heart of the city: a market, a place of assembly, a stage for public ceremonies. It has remained so. Today it hosts concerts, demonstrations and everyday strolls, but its role as “everyone’s square” has never changed.

The dimensions

The square measures approximately 115 metres long by 60 metres wide. It is a generous yet contained space: large enough to hold thousands of people during events, yet enclosed enough by the surrounding buildings to give you the feeling of standing in an enormous open-air courtyard.

A detail many visitors only notice afterwards: the centre is slightly raised, on a stone platform the Bolognesi call “il Crescentone” — a name inspired by its resemblance to the local flatbread, the crescentina.

The four sides of the square

The beauty of Piazza Maggiore is that each side tells a different story. It is worth making a full circuit, unhurriedly, taking in one building at a time.

Basilica di San Petronio (south side)

The building that dominates the square — impossible to miss: enormous, with its unfinished façade — white and pink marble on the lower section, bare brick above. This is neither accident nor neglect: the façade was simply never completed, and that contrast has become one of Bologna’s most recognisable features.

The numbers help put the scale into perspective:

• Construction began in 1390.
• 132 metres of internal length.
• The sixth-largest church in Italy and the largest Gothic brick church in the world.

Admission is free. It is worth stepping inside even just for Cassini’s meridian: a bronze line traced on the floor by the astronomer Gian Domenico Cassini, completed in 1657. At 66.8 metres it is the longest meridian in the world: at solar noon, a ray of sunlight entering through a hole high above strikes the line at the point corresponding to that day of the year.

For photography inside the basilica and access to the side chapels (separate admission, around €5), refer to the information on site or the basilica’s official website.

Palazzo d’Accursio (west side)

Opposite the basilica, closing off the west side. This is Bologna’s town hall: its origins date to the late thirteenth century (around 1290) and it still houses the City Council, as well as the Municipal Art Collections and the Biblioteca Salaborsa.

Two things worth knowing:

• Admission to the Salaborsa (the public library) is free: go in to see the glass floor through which the archaeological remains of Roman and medieval Bologna are visible beneath your feet.
• On the building’s tower sits the Torre dell’Orologio (Clock Tower), which is open to visitors and offers a 360° view over the city — the official alternative recommended when the Torre degli Asinelli is closed.

Palazzo del Podestà (north side)

On the north side, the Palazzo del Podestà with its tower (the Torre dell’Arengo). Beneath it, the vaulted passageway creates a curious and much-loved acoustic phenomenon: the “whispering arch”. Stand in one of the four corners of the vault and speak softly towards the wall, and whoever is in the diagonally opposite corner will hear you perfectly clearly, despite the distance and the surrounding noise. Try it: it is the favourite game of visitors of all ages under the portico.

Palazzo dei Banchi (east side)

The east side is closed by the Palazzo dei Banchi and its long monumental portico, the Pavaglione: a row of sixteenth-century arches designed to bring order to the market stalls and merchants’ benches that once lined the square. Today it is one of the most elegant covered walkways in the centre, connecting Piazza Maggiore to the streets of the Quadrilatero, the historic market district.

The Fountain of Neptune

A few steps away, beyond the flank of Palazzo d’Accursio, the adjacent Piazza del Nettuno opens up around its fountain — one of the defining images of Bologna.

The Fountain of Neptune was created by Giambologna (the statue) and Tommaso Laureti (the architectural and hydraulic structure) and completed in 1566. The bronze statue of the god of the sea stands approximately 3.2 metres tall and has been nicknamed “il Gigante” (al Żigànt in dialect) by the Bolognesi, in tribute to its commanding presence.

Neptune holds his trident in a gesture of authority, while four nereids and four putti with dolphins complete the scene around the base.

It is one of the most photographed spots in the city. For a clean shot, go early in the morning or at lunchtime, when the square is less crowded.

When to go

Piazza Maggiore changes character with the hour:

• Early morning (8–10): almost deserted, soft light, ideal for photographs and for visiting San Petronio in peace.
• Afternoon: lively, full of people sitting on the steps, perfect for watching Bolognese daily life unfold.
• Evening: the illuminated palazzi create a different atmosphere; in summer the square hosts open-air cinema screenings (seasonal programme — check year by year).

How to get to Piazza Maggiore from the station

Piazza Maggiore is in the heart of the historic centre and is reachable on foot from the station, with no need to take a bus.

From Bologna Centrale, take Via dell’Indipendenza: it is the pedestrianised, arcaded avenue that runs straight down to the centre. Follow it to the end and it brings you directly to Piazza del Nettuno and, immediately after, to Piazza Maggiore.

A significant advantage: most of the route runs beneath the portici, so even in the rain you walk almost entirely under cover. Bologna’s portici have been a UNESCO World Heritage Site since 2021.

From Piazza Maggiore, you are also five minutes from almost everything else: continue east along Via Rizzoli and in a short while you reach The Two Towers of Bologna; behind the towers opens the Quadrilatero with its markets.

Practical tips

Comfortable shoes. The historic centre, the square included, is entirely paved in stone: no high heels, especially on the Crescentone.

The steps of San Petronio. Sitting on the steps to take in the square is a local tradition of sorts, but it remains the entrance to a church: keep your behaviour respectful.

Combine your visit. In half a day, starting from the square, you can also take in the Two Towers, the Quadrilatero and the Archiginnasio: the full itinerary is in the guide What to see in Bologna near the station.

ZTL. The square is in a restricted traffic zone: you cannot drive here. If you have a car, leave it outside the old city walls or in a park-and-ride facility.

Water. There are public drinking fountains in Piazza del Nettuno and in the streets of the Quadrilatero.
