Milan Cathedral (Duomo di Milano)
Construction started in 1386 and the final details were finished in 1965 — the city couldn't stop adding to it.

The largest church in Italy took 579 years to complete. Beneath the floor, a 4th-century octagonal baptistery from 335 AD is open to visitors. Above ground, Milan's streets still radiate outward from this exact spot — the same central site as Roman Mediolanum's public basilica, which faced the forum.
What to look for
- The Battistero Paleocristiano (335 AD) — the old octagonal baptistery accessible beneath the cathedral floor
- Milan's street grid: roads either radiate from or circle the Duomo, tracing the city's Roman layout
- The building's 579-year construction arc, from Archbishop Antonio da Saluzzo's groundbreaking in 1386 to the final details in 1965
The underground baptistery is accessible from inside the cathedral — ask at the entrance.
