Saint Ambrose is Milan's patron saint - Construction of the basilica began in 379, and in 387 it was consecrated by St. Ambrose. Over the centuries the basilica has been modified, enlarged, damaged and even bombed, during the last World War.
Despite this it has retained its air of austerity and solemnity, and is still considered one of the finest examples of Romanesque architecture in Lombardy. Inside there are monuments, works of art, and relics bearing witness to sixteen centuries of history.
