Basilica di San Simpliciano (Basilica of St. Simplician), Milan

This basilica dates back to the early days of Christianity, with its construction beginning in the 4th century. Dedicated to Saint Simplician, an early Christian martyr who served as the bishop of Milan at that time, it has undergone several renovations and restorations over time, including significant ones during the Romanesque and Gothic periods, resulting in its present-day Romanesque appearance. Despite the renovations, the basilica remains the second oldest known Christian church with a Latin cross layout.

The bell tower, situated on the right side of the facade, was lowered by 25 meters in the 16th century due to Don Ferrante Gonzaga finding it annoying that it was higher than his castle, which was a common practice at the time.

Inside, the basilica's side chapels feature decorations from various eras, including the Renaissance, Baroque, Rococo, and Neoclassical. The right transept houses a painting by Alessandro Varotari depicting the "Defeat of the Cammolesi", while the apse vault features what is considered Ambrogio da Fossano's masterpiece, the "Incoronation of Mary".
