The Duomo's Romanesque neighbor has a 16th-century facade and a 12th-century body, but recent excavations have revealed the structure is actually five layers deep.

It sits atop a much older Lombard church that served until the early 700s as Lucca's cathedral, which in turn was built atop a 4th- to 5th-century-A.D.

paleo-Christian church that took the place of a Roman temple built atop Roman houses.

In all, 12 centuries of history jumble together in a confusing but interesting mélange beneath the pavement inside (well signed, nonrestrictive use with a handout to help you figure it all out).
