Genoa has long been an important commercial and military port. The medieval district of the city holds many teatures, such as the Porta Soprana (the old stone entrance gate to the city), the Church of Sant’Agostino (next to the Museo dell’Architectura e Scultura Ligure), the beautiful Church of San Donato and the Gothic Cathedral of San Lorenzo. Outside the medieval district, Via Garibaldi, where many of the city’s richest inhabitants built their palaces, is a beautiful walk, taking in Palazzo Podesta, Palazzo Bianco (now an art gallery with paintings by Van Dyck and Rubens) and the magnificently decorated Palazzo Rosso (adjacent to Palazzo Bianco and housing paintings by Titian, Caravaggio and Durer).
