Sant'Eustorgio basilica is to be found in a simple square shaded by trees and though her façade is modest it is one of the most significant monumental complexes of town. The Basilica was founded in the 5th century by Bishop Eustorgio II, on the remains of a much more ancient one. Toward the end of the 11th century, the church was rebuilt according to the Romanesque solid forms, and so it remained until Federico Barbarossa did not destroy it almost completely, and in 1164 took a Roman sarcophagus to Cologne in which, following tradition, the relics of Three Magi are contained.
