The Church of Saint Christopher, located in a suburb of Milan, looks rather odd at first glance. Only after taking a closer look do you realize that it actually consists of two different structures. The one on the left is dated by historians to various periods - from the 7th to the 14th century. The distinguishing features of this structure are the semicircular apse and the entrance portal, which is crowned by a low-set rose window.
The structure on the right is confidently dated to the late 14th and early 15th centuries and is called the Ducal Chapel. According to legend, it was built thanks to Duke Gian Galeazzo Visconti; however, some sources report that the construction of this church was paid for by local residents, who believed that the plague raging at the time could be driven away by prayers and good deeds.
Be that as it may, two centuries after the appearance of the Ducal Chapel, the walls between the two churches were demolished, thus creating a single church with two naves and different roofs.
