Just 50km from Milan, in the Alpine foothills, Bergamo is the most striking city in Lombardy. Structured in two levels, the lower city is more modern and dynamic, whilst the famous 'upper city' boasts a stunning historic centre full of monuments and works of art. In the area around the city the Iseo Lake is well worth a visit, as is the sanctuary at Caravaggio and Crespi d'Adda, the most important company town in Italy, listed in the World Heritage List by UNESCO.
