The Citadel stands witness to the Visconti family’s rule over Bergamo, which began in 1332 and lasted up to 1428, when the city passed under Venetian domination. Built in 1379 when Rodolfo Visconti commissioned the construction of the garrison’s housing units, the complex, known as the Hospitium Magnum, has undergone numerous interventions. The Visconti porch with its pointed arches was restored from 1958 to 1960.
