Bologna is famous for its extensive network of porticoes, covered walkways that line the streets of the city. Take a leisurely walk along the porticoes and admire the unique architectural feature. The porticoes provide shade in the summer and shelter from rain or snow in the winter, making them a practical and beautiful characteristic of Bologna. Explore the longest portico in the world, the Portico di San Luca, which leads up to the Sanctuary of the Madonna di San Luca and offers breathtaking views of the city.
