In terms of location and environmental characteristics Casteggio's are some of the most beautiful views in the area like the panorama from Certosa Cantù, a splendid eighteenth century residence which now hosts the collections of the Civic Archaeology Museum and the Civic Library with its multimedia space. Another splendid view is to be had from the small village of Mairano with its nineteenth century Villa Marina whose guests have included Giuseppe Mazzini. The dome of Pavia cathedral and the Alps are visible on a clear day from its verdant vineyards.
