The basilica is one of the first churches built in Milan. Sant’Ambrogio wanted this building in IV cent. and it was finished only under his successor San Simpliciano, who was buried there. In the year 398 the basilica welcomed also the relics of three martyrs: Sisinio, Martirio and Alessandro. In the interior, in the apse basin, the great coronation of Maria, a fresco by Borgognone. The church is linked to the memory of the battle of Legnano: the windows of the façade represent the “Glorie del Carroccio” (glories of the Carroccio).
