Basilica di Sant'Ambrogio

In this church, in the crypt, are the remains of Saint Ambrosio (it's common to find people praying for favors, so be careful photographing). I loved the church, it's made of brick that gives a warm look, is of Romanesque style and is very well preserved after several restorations. You'll find a lot of things to browse and if you decide to visit, I highly recommend it, go on the web because you'll find lots of useful information.
