See the past in loco
The starting points are Piazza Maggiore and the Neptune fountain, in the old city. Religious works are a strong feature of Bologna, like the San Petronio Basilica, the San Domenico Basilica and the Santo Stefano complex. Asinelli and Garisenda, the leaning towers, are unavoidable as well. And the art pieces of Pinacoteca, the national gallery, are an absolute must-see.
And then back to the future
Beyond the "haute couture" stores of the shopping circuit, especially in the old city, Bologna has an essential influence on the national gastronomy. You must try the ragu (bolognese sauce), the tagliatelle and the tortellini. At night, fun will go on for hours in Via Zamboni, Via Mascarella and, of course, the Piazza Maggiore.
