Construction began in 1396 and went on, with long interruptions, for centuries, so the cathedral reads as a short course in Lombard architecture. The façade, built between 1457 and 1486 in Musso marble, is late Gothic and Renaissance at once, and most of its sculpture is the work of the Rodari family. Inside, the plan is a Latin cross about 87 metres long, crowned by Juvarra's dome, which rises 75 metres.
The setting is part of the pleasure. Piazza del Duomo is a few minutes' walk from the lake, beside the medieval Broletto, so the cathedral fits naturally into a morning in the old town. Inside you will find nine tapestries woven in Ferrara, Florence and Brussels at the end of the 16th century, and paintings by Bernardino Luini and Gaudenzio Ferrari. Allow forty-five minutes to an hour for the visit.
