Basilica di Sant'Ambrogio (Basilica of St. Ambrose), Milan

Saint Ambrose, Milan's patron saint and one-time superstar bishop, is buried in the crypt of this red-brick cathedral, which he founded in 379 CE. It's a fitting legacy, built and rebuilt with a purposeful simplicity that is truly uplifting: the seminal Lombard Romanesque basilica, considered to be one of the most ancient churches in Italy and one of the most historically interesting medieval buildings in Lombardy.

Over the years, the cathedral has undergone several restorations and partial reconstructions, culminating in its current appearance in the 12th century. The structure is adorned with two bell towers: the right one, called dei Monaci ("of the Monks"), dates back to the 9th century, and exudes a defensive severity typical of such structures. The left tower, higher than the former, was constructed in 1144, with the last two floors added in 1889.

As you step inside, you will be greeted by shimmering altar mosaics and a biographical golden altarpiece that once clad the saint's sarcophagus. The shadowy vaulted interior of the cathedral is brilliantly illuminated by these stunning artworks, taking visitors on a journey back in time to a bygone era.

Why You Should Visit:
The impressive architecture is best to be seen from afar and you won't be disappointed at entering. You won't find fancy, elaborate gilded decorations but will be able to see 6th-century columns, a 4th-century mosaic, a 10-century ciborium, medieval statues, Renaissance frescoes and a magnificent golden altar from the year 835.
