Look up at the skyline of the basilica, and you will see something quite rare for an Italian church: twin bell towers rising from the rear. While many Italian campaniles stand alone, these symmetrical giants reveal a fascinating cultural secret. The Benedictine monks who rebuilt this church between 1050 and 1095 were influenced by architectural styles from Burgundy and Normandy. This northern touch gives the basilica its unique, vertical silhouette, a style that traveled across the Alps and settled here in Lombardy. As you walk around the exterior, pay close attention to the windows of the choir. They are framed by intricate carvings of animals, flowers, and geometric patterns, crafted by the famous Comacine masters—highly skilled medieval stonemasons who were renowned throughout Europe for their mastery of stone. For a practical tip: try to visit in the morning when the light hits the facade, highlighting the noble simplicity of its gray stone blocks.
