Duomo di Milano -

Known by its citizens as Duomo di Milano, Milan Cathedral is the city's most recognized historic landmark. Among the world's largest cathedrals, construction on this magnificent religious building began in 1386, but its facade wasn't completed until the early 1800s. The final architectural flourishes were signed off in 1965.

Underneath Piazza del Duomo -

Milan's cathedral is full of surprises, one of which is found underground. At the front of the Duomo, you can descend under Piazza del Duomo into the 5th-century foundations of the Basilica di Santa Tecla and the ruins of Battistero di San Giovanni alle Fonti, which date back to the 4th century.

Santa Maria delle Grazie -

The rather austere-looking red brick facade of the 15th-century church of Santa Maria delle Grazie is lifted somewhat by its impressive six-sided dome designed in the finest Early Renaissance style. But hidden behind the walls is one of the world's greatest art treasures.

Santa Maria Presso San Satiro -

This Italian Renaissance structure doesn't look like much from the street. But step inside and you're met by a grand, vaulted sanctuary that's celebrated for its false apse. At first glance, the interior appears quite large. But walk forward a little and the apse starts to disappear. The expansive dimensions are an optical illusion, an early example of trompe-l'œil, attributed to canny 15th-century Italian architect and painter Donato Bramante.

Museo Poldi Pezzoli -

The private collection of the 19th-century Italian nobleman Gian Giacomo Poldi Pezzoli is showcased at this quirky and engaging museum. The display is notable for its wide assortment of northern Italian and Flemish artists, as well as jewelry, silver, bronzes, porcelains, armor, and weapons.
