In Via Torino, which is a street that starts at the end of the Duomo square, there is a little, old and hidden church that has something astonishing inside. Built in the 9th century A.D. for Saint-Satiro, brother of the most important Saint of the city, Sant’Ambrogio, it was renewed during the 15th century by Galeazzo Maria Sforza (the duke who lived in the Castello Sforzesco, as you can guess from reading his surname) and carried on by Ludovico il Moro.

The most interesting thing about this Renaissance church is the choir you find inside immediately when you get in. At a first glance, it looks so deep, and you think there’s so much space in that area, but actually it’s just painted. This is one of the most interesting masterpieces of the art of the Italian Renaissance, and it was made in this way because there was no space; therefore, they decided to paint a fake choir that still fascinates all real art lovers to this day.
