The Porticoes of Bologna: A Comprehensive Guide for Tourists

In 1288, Bologna’s city government passed a law that still shapes how you’ll walk through the city today: every new house had to include a portico, and every existing house without one had to add it. The minimum dimensions were set at seven Bolognese feet, roughly 2.66 meters, in both height and width, specifically so a man on horseback could pass underneath without removing his hat. That single medieval ordinance is the reason Bologna now has around 62 kilometers of covered arcades running through and beyond the city, more than any other place on earth, and why UNESCO listed the porticoes in 2021 not as decoration but as functioning civic infrastructure that’s been continuously used for over 700 years.

Why they’re brick and stone instead of wood

The earliest porticoes, dating back to at least 1041, were timber, cheap and quick to build during Bologna’s rapid medieval expansion. That changed in 1568, when the city’s pontifical governor issued a decree banning new wooden porticoes after fire risk became impossible to ignore, and future arcades had to be built in brick or stone. A handful of wooden survivors still exist if you know where to look, tucked into Via Marsala and the Corte Isolani, and they’re worth detouring for precisely because they’re a dwindling, fragile category rather than the norm.

The climb that separates tourists from locals

Everyone photographs the porticoes downtown, but the one that actually tests you is the Portico di San Luca, the longest covered walkway on the planet at 3.8 kilometers, strung together from 666 arches and climbing 489 steps up a hill 300 meters above the city to the Sanctuary of San Luca. It starts at Porta Saragozza and takes most people 45 minutes to an hour to walk end to end, and it’s a genuine hike disguised as a stroll, since the covered arcade lulls you into forgetting you’re gaining serious elevation the whole way. I’d argue this is the single best thing to do in Bologna that most short-trip visitors skip entirely in favor of the historic center, and that’s a mistake, because the view back over the city roofline from the sanctuary at the top is worth the climb by itself.

What to actually walk past downtown

The Portico of Santo Stefano fronts the Basilica of Santo Stefano, a complex of interconnected churches built over what was once a pagan sanctuary, and it’s one of the oldest continuously used religious sites in the city. Near the university, the portico running past the Archiginnasio palace, built in 1563 as the original seat of the University of Bologna, one of the oldest universities in the world, gives you covered walking right up to a building lined with the coats of arms of centuries of visiting students. Via Zamboni and Via Indipendenza both offer long uninterrupted stretches of 18th and 19th-century arcades that double as the city’s main shopping streets, so you can browse, eat, and sightsee without ever stepping into direct sun or rain.

One correction worth making here: the Basilica di San Petronio, the city’s patron-saint church and one of the largest brick basilicas in the world, is often confused with the Basilica of San Vitale or the mosaic-famous Neonian Baptistery, which actually belong to Ravenna, a separate city about an hour and a half away. Bologna’s own basilica is famous instead for its unfinished marble facade, still bare brick above the lower third, a stalled Renaissance project that was never completed for reasons still debated by historians.

Getting the most out of a walk

Bring comfortable shoes regardless of weather, since the porticoes cover enough distance that you’ll rack up kilometers without realizing it. Rain is actually the best time to appreciate why this infrastructure exists at all; walk the arcades during a downpour and you’ll understand immediately why medieval Bologna decided covered streets were worth legislating. Look up as you walk. Ceiling frescoes, carved capitals, and painted vaults vary wildly block to block, and most visitors never glance above eye level. If you want a meal under cover, the porticoes near Via Pescherie Vecchie and the old market streets are lined with small trattorias that spill tables out under the arches, which is as close as Bologna gets to an all-weather outdoor dining scene.

Start the San Luca walk in the early morning if you’re doing it in summer. The climb has almost no shade breaks outside the arcade itself, and starting before the heat builds makes the 489 steps considerably more manageable.
