Genoa (Genova) is a port city and the capital of northwest Italy’s Liguria region. It’s known for its central role in maritime trade over many centuries. In the old town stands the Romanesque Cathedral of San Lorenzo, with its black-and-white-striped facade and frescoed interior. Narrow lanes open onto monumental squares like Piazza de Ferrari, site of an iconic bronze fountain and Teatro Carlo Felice opera house.
